Comments: These shoes are very narrow. If your feet are wide don't go for these. I could';t use them, as they were pressing my side and making my big toe numb.
From: Luis, 11/12

Comments: Ok, I've been through several pairs of 3.3's, and they are sturdier than the 4.3's. The 4.3 is lighter, but that's about the only improvement. The toe box is too mushy, and the straps are way to movable and appear to be susceptible to breaking. I'd like Nike to go back to the 3.3 but make them lighter. Disappointed.
From: Lin, 8/12

Comments: I play 4 times per week and I have had these shoes for 3 months and have broken one strap. The lacing system is working fine. You will wear out the soles before you break the lace straps enough to cause actual problems. The main problem with these shoes is that they are narrow. Durability is excellent though. Highly recommended if you have narrow feet!
From: Eric, 8/12

Comments: Buy them if you like Rafa, don't buy them if your a serious tennis player that plays a lot. The lacing system is poorly designed and the loops will dry rot and break well before you will wear out the soles. The shoes do feel nice but when the lace system fails during a match you're going to be more than pissed off. Nike needs to fix this disaster of a design. They may look cool, but they don't perform! Try the new barricades if you want a shoe that is durable.
From: Randy, 8/12

Comments: They needed a little break-in and they felt a bit snug at times on my one wider foot. I totally agree about the short tongue thing, but I like the shoe.
From: Lee, 7/12

Comments: I just ordered the Blue/Green 4.3's in a 10.5 because they were cheap, only $79! I tried them on previously at a Tennis Shop. Definitely way more generous than the 3.3's which I didn't even bother trying to slip my entire foot in. Very comfortable for the 4.3's, glove-like around the foot which is great. Can't comment on durability obviously because I don't even have them yet, but if they last like the 2.3's, they should be just fine. Might order the Peach one or even the Scarlet one later if they drop because the anthracite on the peach looks good and the scarlet when it's in the sun looks pretty dang sick. I wish Nike would do last year's 3.3 colors for the 4.3's because I have to admit, the 3.3's looked awesome. Oh well, still a great steal for $79 with free shipping and the 6 month durability guarantee!
From: Will, 7/12

Comments: I used these shoes in my most recent tournament and love them. I've always used Babolat shoes but these are for sure the most comfortable shoe I have purchased!
From: Kipper, 7/12

Comments: I got a pair of these, and had to send them back! I have slightly wide feet and I could barely get my feet in them. It felt like they were getting squeezed. I like a little wiggle room on top for the toes and these had absolutely none. I had pressure on all sides of my foot. I've tried Nike Cage 2's and Courtballistec 3.3's, and Asics Resolution 1, 2 & 3's, but the Nike Breathe Free II's are still the best tennis shoe I've ever had.
From: Ron, 7/12

Comments: This is a very good shoe, but it has some fundamental design problems. I came from the great Nike Cage II Breath Free (went through 6 pairs of these babies) and these CB 4.3s have a similar fit and similar cushioning and weight. Minimal break-in. Very sturdy sole. Great support and stability. And good looking! However, there are some design problems in my opinion. First, the tongue is too short. The laces barely stay on the toung and you cant use the last lace hole or they will fall off onto your foot. Just a 1/2 inch more please Nike. Second, there are two seams in the inside of the heel cup where there should be none! This is a no-no for all athletic shoes because of all the rubbing that occurs in this area. Also the material used in the heel area does not look as durable as the great Cage IIs. Third, as others have mentioned the lacing eyes are actually straps. These straps connect on one end to the lace opening in the shoe, and on the other end to the inside insole of the shoe so that they wrap around the sides of your forefoot. This is weird. It doesnt provide any benefit that I can see and the lace system seem vulnerable to various possible failures. Maybe Nike thinks this makes the shoe look better, but I'd prefer functionality. Have only had mine for a few weeks, so no problems with anything yet.
From: Victor, 7/12

Comments: The 4.3 is the best shoe yet. It is comfortable right out of the box. It has good support and cushioning on the heal. In my opinion it is a lot more comfortable than the 3.3. It looks great and plays great. I can't say enough about this great shoe. I highly recommend them and I just ordered my 2nd pair. Great job Nike!
From: Michael, 7/12

Comments: I like these shoes but the eyelets that hold the laces keep on breaking on me. They are just held by a piece of fabric and they are not duable at all. Once they break you can't lace your shoes. Won't buy these again until this is fixed. It didnt happen with the 3.3's.
From: Ryan, 7/12

Comments: I just got the new red colorway that Rafa wore at the French. This is not the same shoe Rafa wears. The tongue is way too short. Look at what Rafa wears. Normal length tongue. I have 2 colorways and both have short tongues. The 4.3's are good but I do like the 2k11 better. The 2k11 fits me better and has the better lacing system and needed no break in. I have not had a problem yet with the lace loops on the the 4.3's but I have over 10 pairs of shoes so they don't get worn as much as if they were my only shoe. This is a problem waiting to happen.
From: RL, 6/12

Comments: This is the best shoe so far from Nike. Good for my flat feet with "superfeet" orthopedic inserts. Great support and never seems heavy! A winner in my book.
From: Bill, 6/12

Comments: Nice looking shoe with good support but I wholeheartedly agree with the comments about the flimsy lacing system. I had one of the loops break after playing about three hours. I would expect Nike to do a better job play-testing its shoes before putting them on the market. Who wants to spend $130 for a pair of shoes and then have to drill a hole (or multiple holes) through the upper to make up for a shoddy lacing system? What is a player supposed to do when the lacing breaks during a match? Who wants the colossal hassle of sending shoes back to TW for replacement? All reasons not to buy this shoe.
From: John, 6/12

Comments: So far I have really liked these shoes. I have had them for about a month and a half now and they are insanely comfortable on my feet. I have wider feet and thought I would have problems with arch pain but did not have any pain at all. Also, they are a great looking shoe! They were also very easy to break-in. Maybe just a couple of hours before the stiffness went away. Thank you Nike!
From: Andrew, 6/12

Comments: I love these shoes and the support and stability that they offer. I use custom orthotics with them and for me they are as good as it gets and I've tried many of the most popular tennis shoes including adidas Barricades and the Babolat Propulse (I think that's the name). The one problem is the lacing system. The older version laced through the shoe and was great but the current version laces through loops that always break. It is only a question of time Fortunately, Nike has been very cool about exchanging the broken shoes for new ones so I keep wearing them. I have had this happen so often and have had so many new pairs that I feel like I'm sponsored by Nike. The last pair broke after only 3 weeks of pretty mild usage. I don't know why Nike doesn't fix the issue.
From: David, 5/12

Comments: Solid Shoe. Have been wearing Asics the past several years, but after the Gel Resolution 4 failure to widen the toe box, I had to switch brands. Much lighter in feel on court than when you pick out of the box. Very easy break-in and comfortable feel right off the bat. Well cushioned. I beat up shoes so hopefully these will have some durability. My only issue is the moronic use of cloth/fabric for the lacing grommets...what was Nike thinking??? This area will obviously be the first area that will break down thus rendering the shoe useless. Outside of the lacing, this is a solid shoe.
From: CWS, 5/12

Comments: I have been wearing Courtballistecs since the 2.3s and I must say that these are the best of the bunch. Last year I didn't feel like getting the 3.3s until they went on sale so I picked up one of the few Breath Cage IIs left. Coming from the 2.3s I was wondering why did they stop making these, the 2.3s hurt my knees and turned me into an ibuprofen junkie. Then after I destroyed them I picked up the 3.3s and they weren't on par breathing wise or comfort but a pretty good shoe(my laces didn't break so I can't complain), but anyway I got two of them and then using my product voucher I bought the 4.3s. These are really good, cushioning is excellent, breathability is closer to that of the BCIIs and it is very stable and comfortable. All in all these are going to be stocked up but, I wish that they still made the BCIIs even if they didn't have the 6 Month Outsole Guarantee.
From: Chris, 5/12

Comments: This is the first pair of Courtballistecs that I could take from the box and play a match in. Comfortable from the first moment I laced them up with just the right amount of snugness all around. Roomier than the Courtballistecs 3.3 and without the three-week break-in period that I needed with the previous model. The weight seems just right for such a supportive and durable shoe. My biggest worry is the lacing system. It uses the same ribbon loops of the Courtballistecs 3.3 and I broke 3 of those before I sent the shoe back to Nike. I don't lace tightly and the ribbons make for a quick lace-up and shoe removal but aren't tough enough for the job. My Courtballistecs 3.3s cost $125 and I was drilling holes in the shoe to run the laces through. Not cool! I like the new color; grey with peach. I've never seen that combination before and I like the subtle splash of color. Over time, I learned to love each of the Courtballistecs and this one is on pace to exceed them all. I may end up stockpiling this model because I don't know how it can get better.
From: Michael, 5/12

Comments: I am a tournament level player and enjoy the great comfort that comes with these shoes. The one problem I feel is the outsole wearing out quickly but it is ok because there is a warranty.
From: AKA, 5/12

Comments:Four major problems still exist in this shoe having not been fixed from the very similar Courtballistec 3.3: 1) There is nowhere near enough padding around the front of the ankle collar so the front inside of both ankles gets bruised. It's very painful and does not improve after break-in. 2) The "loop" lacing system is already starting to fray. Being identical to the 3.3s, then they do break the shoes become unwearable. Use proper holes like all other companies on your heavy duty tennis shoe. 3) The tongue is too short. 4) The laces are way too short. If the last two points seem petty, they are not when you are spending $130 yet Nike is nickle and diming you. Overall the shoes are solid, with lower weight than the 3.3, better ventilation and still hard wearing but I will be going with Adidas Barricade 7s for next year if these things aren't improved for the CB5.3. The CB 2.3 had none of the above 4 problems which sprout from cheapness and really do make what could have been another 5-Star Nike shoe into a 3- star one.
From: Nicko, 5/12

Comments: This shoe is a great shoe. I had upgraded from the 3.3's, and they are a major breakthrough. There is almost no break in required, and it is noticeably lighter. Like the 3.3's, the loops holding the laces still break, so try not to lace them too tight. Also, near the drag on 2X, the cloth holding the sole to the drag on 2X ripped. Got them sent in today, and getting a new pair. they are very durable, like the 3.3's, and very stylish. The part near the AirMax wears out pretty fast, so dont drag your feet. But all in all, they are very good shoes, with good durability. Just a few flaws at the part where the shoe bends (drag on 2X) and the laces. Good Work, Nike!
From: Anon, 5/12

Comments: Bought these shoes after my 3.3s started wearing down and holes formed on the front toes of the shoes. 4.3s come to the rescue. The shoe is lighter and much more comfortable than the 3.3s. At first glance I was concerned about the design of the upper because it seemed somewhat flimsy compared to my 3.3s. Lo and behold after one set of playing with these shoes the upper began to split apart at the point where the laces loop into the shoe. Unbelievable! Less than an hour of playing and these shoes are already done. It is a great looking shoe and very comfortable but someone really dropped the ball with the design of the upper. It's too bad the 6 month warranty does not cover the upper because this appears to be a common problem.
From: Victor, 5/12

Comments: This is a good shoe, but there is a MAJOR FLAW. As the previous poster stated, the loops that the laces go through break which is what allows you to tighten the laces. This is very disappointing because otherwise it's a good shoe. Nike, didn't you do any testing?
From: George, 5/12

Comments: I really like these shoes, but they have one major flaw regarding durability. The loops that the laces go through are cheap fabric and they start to break after a very short period. I have a narrow foot and I pull the laces tight. After only 1 month the first lace loop broke and after 2 months, 4 had broken. I had to use a drill and make lace holes for the laces to go through. One of the reasons I bought these shoes is that Nadal is very tough on his shoes and he pulls his laces very tight. I figured they would hold up, but they don't.
From: Marcus, 4/12

Comments: I used to wear Vapors but I tried this first time tried Court Ballistecs Vapor wear out quite fast on hard court. Not really happy with the weight and slightly tight at the front. Quite long lasting though..
From: Sherry, 4/12

Comments: I also wear a size 9 and I got these today, and played with them immediately after. They were great! They felt a little tight on my feet and I definitely need to get a thinner insole, but they're great!
From: Aksel, 4/12

Comments: Great shoe. I wear a size 9 and with the insole they were way to small. The insole is very thick. I took it out and replaced it with a thinner one, and problem is solved. Other than that it's a great shoe. My new go to shoe. Very happy with my purchase.
From: Gene, 4/12

Comments: This new 4.3 fits me snug and comfortably at the same time. Now in comparison to its predecessor the 3.3, its noticeably lighter, little to no break in time and the support is phenomenal. I use sofsole fit insoles because it comes with an iffy one just like any other shoes out there. Now on to the only flaw is the sole durability. It felt like it was less than the 3.3. I have only had it for over a month and its showing a lot of wear on the toe, and some on the heel. This great shoes need to come with a more durable sole. Maybe next year?
From: Ian. D, 4/12

Comments: I have had my 4.3's for 4 weeks and I play on average 3 hours everyday and the bottom looks the same as the day I got it out of the box. It feels great but only one problem with this that my foot gets BLISTERS!!!!! My right heel is bright red.
From: Joey, 3/12

Comments: Like John above I think these are the best tennis shoes available, better then the 2.3 or that Adidas Barricades V (I still have an almost brand new pair, that I don't like to play in, being too clunky by comparison with the Ballistecs).
From: Marian, 3/12

Comments: For whatever reason these shoes hurt the outside bottom of my foot especially my right foot. I have never had this problem with shoes prior to these. Right now I am up to wearing them for about 20 minutes before I have to take them off. From what I can tell the inner foot bed is somewhat raised in the middle and the higher sole is placing stress on my somewhat pronated foot. I am hoping they will break in or I may have to try modifying the insole.
From: Greg, 3/12

Comments: In response to the comment below, Rafa gets custom shoes. In fact, he has completely different insoles from the stock, customer-based 4.3s that are sold, as well as an extra-long tongue. I also noticed that after breaking the tongue in, as odd as that sounds, it actually feels more comfortable at a shorter distance. Trust me, after a while, it will be fine and you'll still love the shoe.
From: Anon, 3/12

Comments: Great shoe right out of the box with little to no break in. Night and day difference from the 3.3 of last year. Much more comfortable and wider in the toe area. Only complaint is the tongue is about an inch to short. If you use the last lace to lock your heel down, the laces end up on top of your sock due to it being so short. Hopefully Nike will fix this soon. I did notice Rafa's shoes during a recent match and it appears his have been fixed already. All in all one of nike's best ever. Highly recommend.
From: Anon, 3/12

Comments: First off, the 4.3's replaced my last pair of Breathe Free 2's (which I stockpiled). To my surprise, the 4.3's provided a better fit in the heel, the arch, and toe box. The 4.3's feel very secure. The heel is well cupped and comfy, the arch fills my medium to high profile nicely, and the wide lateral area is very stable. The shoe locks you in. Fills all the gaps. It is very well cushioned, too. They do not feel elevated. I thought they might compared to the BF2's. The forefoot has nice flex and the toe box gives me room and comfort. Not once did I think about the shoes on my feet while I played today. I felt very confident and secure in them. Perfect right out of the box. Bottom line, nice secure fit, great comfort, great stability, light feel, pricey but worth it. Highly recommended!
From: Tom, 3/12

Comments: Definitely lighter and more comfortable than the previous version. These are great right out of the box! Like some of the other users, I forgot I was wearing them.
From: Chris, 2/12

Comments: Great shoe, so much better than the 3.3. Very comfortable right from the second I put it on. Only complaint is that the tongue isn't long enough, other than that this shoe is great. Love it.
From: Tayven, 2/12

Comments: Great shoe that requires little to no break in time. It felt much softer than the previous Ballistec which I could not wear. The arch is of the lower medium variety so the shoe felt a bit intrusive at first but now feels great after some court time. I feel like this is a better compromise to the comforts of the vapor 9's which I have been warned to have durability issues. Those who are interested will not be disappointed if they purchase.
From: Anon, 2/12

Comments: A really great shoe! I have been using Nike products for the past 7 years and this is the best shoe they have made. It didn't require any break-in period and has perfect cushioning. Furthermore, fits my wide feet perfectly and offers great durability (no signs of wear-and-tear even after 3 weeks of heavy 4 hour practice a day).
From: Lukas, 2/12

Comments: These shoes are the best in the series, love the padding at the toes, never had a shoe like it! Good work Nike!
From: Aaron, 2/12

Comments: By far, the best pair of sports shoes I've had. Compared to the 3.3, the comfort and cushioning is amazing, and they removed just enough weight. For the first 30 seconds after I put them on, all I can think is, wow, comfy! Then I just forget about them because they fit my feet so well. It might be that I just got lucky and Nike did exactly the right thing for my type of feet - in any case, I'll make sure to stock up on a few pairs while I can, I'm doubtful I'll ever find other tennis shoes that are so perfect for me! (Plus, and that's very subjective, I aesthetically love the blue and green ones, nice vibrant colors).
From: Joki, 1/12

Comments: Best Court Ballistec to date, soft and comfy upper from the Dragon 2x to the stern of the shoe. Flexes really well while giving the right support all round. No break in required for the upper and breathes very well. Lacing system is great and locks my feet firmly down. Sole is similar to the 3.3s, so a quick break in and off you go, very happy with the durability. Excellent with the update and keep up the good work, will buy more.
From: Bryan, 1/12

Comments: It's a great looking shoes. I love it from all area of the court. It definitely breathes better than the air court 2.3. When I drag to reach for a ball, I don't have to worry about anything. I can feel the shoes protecting my feet. However, it is quite expensive.
From: Jack, 1/12

Comments: So far a very nice shoe. Reminds me of the Breathe Free in the same color but with the thicker Air Max sole. The upper is comfortable and moves well with your forefoot while still maintaining support. They are heavier than my Vapors but lighter than I expected. A nice surprise.
From: Anon, 1/12

Comments: The first thing I noticed when I put these amazing looking shoes on was how comfortable they were compared to the 3.3s. It seems like Nike put some extra cushioning in the toe area and also gave them a slightly wider fit. Being a consistent Nike customer, I was prepared to break in these shoes because the 2.3 and 3.3 both required significant break-in periods before they were remotely comfortable (Just watch Rafa accomplish this with the 2.3s at http://www.youtube.com/watch? v=9NIGcNrDxFw) but no serious break-in was required. Unlike the comment below, I did not experience any traction issues, in fact, I thought the traction was much improved. Ventilation and support in all areas were outstanding and my feet didn't ache or hurt in any way after I took them off from playing. I cannot discuss durability, although they look as though they would last just as long, maybe slightly longer, than the previous version. The only downside, although very minimal, was that the tongue was shorter and took a bit of adjusting to get comfortable. To conclude, I would say that these shoes are the best tennis shoe available at the moment and they are worth the $130 price tag.
From: John, 1/12

Comments: Very Pricey..ouch! FINALLY Nike got it right with this 4.3 edition. Very soft compared to their previous model. Nicer fitting width..THANK YOU NIKE! Breathes better too. However could use more arch support. With these I put in my own insoles (spenco) for arch support. A Must! Also the bottoms are slippery..not as sticky like the Adidas Barricades I normally wear. My feet slipped out from under me as I hit a forehand and I fell on my head and neck..it was quite scary. Great shoe for doubles play I suppose. I do like that they have a warranty. My little niece said they look cool! LOL!
From: Jared, 1/12

Comments: These shoes are so nice. The look and feel of these on the court is amazing. Even though the shoes is kind of heavy, it doesn't feel like it when I played. I had these for about three weeks and there is little wear on the soles and inner sides of the shoe. All in all, it was the best $130 dollars I had ever spent on tennis shoes. These are even better than the Propulse 3 and the Barricades. A MUST BUY!
