Comments: The gel resolution 2 was a great shoe but had a significant break-in time and lacked adequate ventilation. The gel resolution 4 solves both of these problems. Good to go out of the box and good ventilation. Lateral stability is very good. With respect to size I measured these against new pairs of gel resolution 2's and solution speeds of the same size (11) and found the length of the 4's to be one-half centimeter longer. That can be a significant difference if your present same-sized shoe fits nicely with reasonable space in the toe box. They are also a bit roomier in the width. Some may be able to get away with tying the same size tighter. Most likely you'll need to go down the recommended 1/2 size. On the other hand these are ripe for replacing the removable insole with a custom orthotic. Great shoe.

Comments: Excellent shoes! There is no break in necessary with these shoes. Please don't listen to the 1/2 size smaller advice. They are absolutely the same size as the previous generation. Just a little roomy at the toes.

Comments: I received the Asics Gel Resolution 4s as Resolution 3 replacement a month ago. I love the design and color more than the Resolution 3. The photos provided do not do the color justice. They look much better in person. These fit exactly like Resolution 3, right out of the box comfort and no break-in required. I think that you only need to buy a 1/2 size smaller if you wear other brands/models such as adidas Barricade 6 or Nike 2K11. I did when I made the switch.
From: Brian, 5/12

Comments: As a first time ever Asics wearer I was taken aback after realizing how well formed this shoe is to my foot. After walking and then playing a few hours on hard court with them I'm still amazed at how comfortably conformed these shoes are. And I'm comparing it to the best ie Nike and Babolat. I also resonate with the acronym. Well done Asics, I'm on my way to 'steal' a second pair.
From: Ron, 5/12

Comments: I've been asking for a warranty on these shoes for sometime and they finally got one. I had quit wearing them because I couldn't afford a $120 pair of shoes every month. With the warranty, you would have thought they'd have beefed up the outsole a bit but they didn't. Wore a hole through the mesh upper within two days. Had to play with that hole for 2 more weeks until the outsole wore through. As much as I love Asics, these are not serious tennis shoes. Too much mesh for heavy side-to-side movement and pounding on hard courts. Sending these back for my free pair and based on how these performed, I will not be purchasing another pair. High performance tennis players should steer clear!
From: Will, 5/12

Comments: For me the Asics Gel Resolution 3 was the best fitting Resolution. The Gel Resolution 4 is not just a cosmetic update. The toe box is narrowed and pointy. I ordered an 11 and 11.5 and neither ones fit, so I had to send both back. Bummed.
From: HCB, 5/12

Comments: I have wide feet and a high arch-instep and these shoes are by far the most comfortable I've ever worn. My shoe of choice has been Nike Vapors -- a great shoe -- but these Asics Gel Resolutions will now be my tennis shoe of choice. I played nine hours of hard court tennis at Dartmouth over the weekend and had none of the tenderness in my feet that I'd expect from my previous shoes. I followed TW's advice and bought a half size smaller and the fit is the best I've ever had. By the way, they fit right out of the box but after 10-12 hours on the court they seem to have molded to my foot.
From: Warren, 5/12

Comments: I've been wearing Asics exclusively since the Gel Resolution 2's, and these incorporate the best features of the 2's and 3's. I did order the 1/2 size smaller, and the fit was more snug than with the 3's. At first I worried I'd need to go up to my regular size, but I tried on a brand new pair of 2's to compare, and the fit was identical. After a few times wearing them, they feel incredible. They have the fantastic fit of the 2's with the added stability and improved durability of the 3's. Plus, it's great to see they made another colorway. Great job Asics and keep up the good work!
From: John, 5/12

Comments: I was wearing Asics Gel Challenger 8's, and loved the fit and stability. Unfortunately, I wore through the soles in both shoes in 3 months. They were guaranteed, and I moved into the Asics Gel Resolution 4's. Nice fit right out of the box, and true to size. I noticed better toe room, and a very light feel. Hopefully they will last a little longer.
From: Alan, 5/12

Comments: After wearing for a few weeks I probably won't buy again. I am a 10.5 and ordered a 10.5, the fit seemed great at first but now my feet ache on the sides, right where the Asics logo meets the sole. It's too tight/small there and after a few hours of play my feet will hurt there all night.
From: Mike, 4/12

Comments: The Asics Gel Resolution 4 is a great shoe. It is very comfortable. I ordered 1/2 size smaller than usual and got excellent fit. Cushioning is excellent. More stable and lasts longer than Nike Vapor 7. Better cushioning than Nike Zoom Breathe 2K11.
From: Joe, 4/12

Comments: I have the R3s. They are awesome shoe for serious hardcore hard court players. I have been playing with the Gel Advantages for two years, was impressed with the fit and cushioning, and decided to give the R3s a try. At first, when I walked around in them, I wasn't impressed; however in their natural habitat, the hard court, I discovered the R3s had the technology that wouldn't weigh me down. It's sleek design gave me an edge moving around on the court. The rubber compound griped like no other shoe. Played with them for the first time yesterday. The mid sole is like having McPherson suspension for your feet! My only regret is I wish I could have purchased them in white. If you prefer the hard courts like myself, I'd highly recommend you try on pair of Asics Gel Resolutions. Asics Gel Resolution: the Resolution to a thousand fruitless searches.
From: Darrell, 4/12

Comments: Been using Nike Vapors for 6 or 7 years, tried the Gel Resolution 4s on and was sold on the fit. I'm tired of wearing out soles in 3 weeks, so I hope the Gel Resolution 4s have good last, a 6 month guarantee is nice. So far I love them, my only minor quip is that I wish the sides came up around the ankles just another 1/4" or so.
From: Mike, 4/12

Comments: I am a long time K-Swiss fan. I have an arthritic knee and asked a TW Rep to recommend a shoe that would be good for my knee. They recommended the Gel Resolution 4's. My normal size is size 12 and the rep recommended size 11 1/2 (1/2 size smaller). I tried the 11 1/2 and they felt really tight in the toe box. So I sent them back and got a size 12. The size 12 felt better but still felt tight in the toe box. I tried to wear the size 12 in the house to break them over 2 days but it did not seem to help. So I called TW and asked them if the Gel Resolution 4's would stretch out after playing tennis in them. They advised they had the same issue with toe box feeling tight and after playing 3 weeks they stretched out and they felt great. So I thought I would try them. So I played in them 1 time and the shoes stretched out and they now feel great. No more issue with the toe box. They seem to be lighter and have more cushion than the K-Swiss Defier.
From: Greg, 4/12

Comments: These fit great right out of the box in my usual size. GR3s needed some break-in time. Support is better than Gel Resolution 3s, too. May be marginally wider but still good for narrow feet.
From: Jim, 4/12

Comments: I ordered the Asics GR4's a 1/2 size smaller as TW suggests. While the shoes were in transit, I then read some of the comments here advising not to follow TW's suggestion to order a 1/2 size smaller. I then began to regret not reading the comments first before ordering and worried about the possibility of having to take the time to return shoes that might be too small. Well, the shoes arrived; I tried them on; and the shoes fit perfectly. Thanks TW for knowing your products well! The shoes look great (Black & Green) and feel great. Before I first tried the Asics GR line, I tried other top models of other name brands but was only satisfied with Nike Air Courtballistics (2.3 only) or Nike Air Zoom Breathes. The Asics GR4 has now become my top pick.
From: P. Simon, 4/12

Comments: came from Head Speed Pro, which I really liked. They don't make them any more, so I tried these. The shoes fit very well around the foot (yes, they are 1/2 smaller size - normal size 12, ordered both 12 and 11.5, and kept the smaller). But I am having really hard time with the way the the sole is designed - my feet seem to be pushing into the heel too much (heel is in lower point relative to the front of the foot). Additionally, the sole is very spongy/soft in the heel (which would be good/comfortable if the foot was positioned forward). The sole design is causing my heel and achilles tendon to be in a great pain. Would love to wear them for comfort, but it's too painful to play in them.
From: Jan, 3/12

Comments: I give the GR4's a 7 out of 10. This shoe feels better than the GR3 but not as good as the GR2. I have a wide foot and the toe box in this shoe is a little too tight. Also, if you like to use different insoles such as Superfeet, I'd order your regular size, not the 1/2 smaller.
From: Greg, 3/12

Comments: I've used Adidas so far, but decided to try something new. Got the GR4 and the Propulse 3. GR4 is a better fit for regular and narrow feet. Propulse 3 should be better for wide feet. Do not get 1/2 size smaller.
From: Dimm, 3/12

Comments: For all who have used the Gel Resolution 3's and thought the toe box to be too big, well go for the Gel Resolution 4's, because they shrank up the toe box enough that I prefer the Gel Resolution 3's and am having a difficult time breaking the new 4's in even after 6 sets. Shoes are different for everyone according to sizing, but the shoe outside of sizing is AWESOME! For those who thought the GR3's were comfortable will find the GR4's a bit tighter in the toebox. Otherwise, they are the same great shoe.  
From: Chris. 3/12

Comments: This shoe was just as comfortable and perfect as all the other Asics I've had. I highly recommend them as the best shoes out there. They definitely run a half-size too big, though. The only thing that concerns me is lateral movement on the court. I've rolled my ankles in these numerous times and the second time I played in them this time I almost did the same thing. I wear ankle braces with them so they're perfect now, but just saying. I keep trying to find something better than Barricades, but don't know if I ever will. I play 2-4 times a week for hours. 4.0 level
From: Scott. 3/12

Comments: This a first time purchase for me with the resolution 4 and after quite a few hours of drills and workouts, I think the shoes are very good. Have been using the kswiss bigshot which I really like and have been using for a long time, but wanted to try something new. The Res 4 fits very well throughout and very secure. The only slight difference I find between the 2 shoes is the heel feels slightly deeper and more secure in the bigshot but it probably will settle in after a few more times on court. I have a medium foot with medium to low arch and find the shoes fits well. Don't use any nike or adidas because I find it hard to get the fit and comfort. Typically play 4x a week on hardcourts and go thru shoes in 3+/- mo's. Hope to get a little more out these. Did not find any difference in sizing as stated in description. Went with my usual size.
From: CD, 3/12 <

Comments: Love the GR4's! Have worn Asics exclusively for the last 2 years and these are amazing. For me, I recommend, don't get them 1/2 size smaller - especially if you were orthotics of any kind.
From: Kim, 2/12

Comments: Having been a convert to Asics tennis shoes since the GR 2's, I've been very impressed with these shoes, and have converted many of my friends. I am currently wearing the GR3's, but had the opportunity to try on the GR4's. WOW! I was very impressed. On the spec, it does not look like anything has changed, but whatever they did, I noticed an immediate increase in comfort over the GR3's and GR2's. I did try it a 1/2 size smaller and I did enjoy that fit better than my regular size, so yes, buy them a 1/2 size smaller. Definitely the most comfortable shoe I have ever worn.
From: Dru, 2/12

Comments: Finally back to being a great shoe!!!! This makes about 12 pair of the various Gel Resolution series I've had over the years since GR1. I took over a year away from them after finding the GR3 to be a very average shoe (really stiff) and an unworthy successor to a really terrific lineage. In the interim, I went to T22s and more recently the New Balance 1187 , with the latter also being a top notch shoe and closest to the early GR versions. This new GR4 seems to be back to the high standard set with the earlier versions which were so impressive, despite durability issues. Immediate comfort, stability, cushioning and support. Re sizing - I ordered my regular size and they fit fine. Don't know why TW suggests ordering a size down.
From: Steve, 2/12

Comments: I was concerned about this shoe being 1/2 size bigger as noted but it was not the case for me (I bought my regular size and fits very comfortably). I love this shoe, not only the classic color of navy blue and white but also the comfort right out of the box. I have used and loved the GR 3 and expect the same quality and durability of the GR 4. A great shoe, especially for three to four hours a day of tennis. Serious players would appreciate the GR4.
From: Humerto, 2/12

Comments: My last 2 pairs of shoes were the Asics Gel Resolution 2 and the Nike Lunar Vapor 8's. I prefer a shoe that is comfortable, light weight, and also durable. I have found that this shoe has really provided me with those things that I desire. Out of all of those things, I was really impressed with how comfortable these shoes are. These are the most comfortable pair of tennis shoes I have ever bought and I have went through several years worth of shoes. Cosmetically, I was a bit worried about the green but it looks much better in person. I would definitely recommend this shoe to anyone. Also, everybody at the courts have been complimenting my shoes. It's a great shoe for someone wanting a light-weight shoe that provides both stability and incredible comfort.
From: Ryan, 2/12

Comments: Fit is snug which is a good thing. And Asics continues to improve this shoe for the most part. And these weight more than the GR2's, and sit up a bit too high for me (coming from a Nike Vapor VI).
From: Anon, 2/12

Comments: Just received the shoes this AM and played 2 sets. Unbelievable comfort right out of the box. I have owned the Res 2's and Res 3's and the 4's are probably best yet. Comfort appears to be same as GR3's, but front shoe box is slightly shorter for a snugger, better cupping fit. Sizing is almost 1/2 size smaller according to recommendation. Examined all cosmetic changes and all appear to improve quality. These shoes are addicting and I have turned my two nationally ranked G-16's twins (formerly Prince aficionados)on to Res 2&3's and they are believers. I have never worn black shoes, but love the new black/green combos. Only thing you need to concern yourself with 1st couple times wearing is that you may actually slip out of shoe on the court on hard cuts until break-in works the natural foot cupping. Buy with confidence.
From: Todd, 2/12

Comments: Love the color scheme. I currently own GR3's, adizeros, cb3.3, zoom breathe 2k11, and the GR4's are the most comfortable (gr3 are a close second). A great shoe!!!
From: Jon, 2/12

Comments: Received my new GR4 earlier this week. I wore them to work twice to break them in. I have not taken them to court yet, but I know they will perform well. Just like all previous GR models these are very very comfortable out of the box. This new model is definitely an improvement over GR3. The cosmetics are great and the problem with the extended toe box is resolved as well. Since discovering Asics shoes 3 years ago, I have not worn any other brand of shoes to the court or gym or track.
From: /Josh, 2/12

Comments: These are a fine, but almost completely cosmetic update to the excellent Resolution 3s. I do not understand the sizing guideline, as they fit exactly the same as the R3s.
