Comments: I love this shoe! First of all, I have pretty wide feet and these didn't pinch at all! I have had three different pairs within a year which is pretty normal since I play year-round. The shoe just works for me and after playing a 3 hour match or even a day at tennis camp, my feet never hurt.

Comments: Shoe does not have high arch support as stated. In fact, if you pronate, this shoe turns in even without your foot in it. Do not buy this shoe if you are looking for the pronation control. It's also a more narrow shoe. If you have a wide foot, don't buy this shoe.

Comments: The Pro C is not the Ultra-Natural. Although it has the same soft upper, nice arch support, and identical sole, it does not offer the same quality of cushioning as the Ultra-Natural. This shoe also seems a bit wider than the U-N, but it may be the newness, and I need to break-in the shoe with tighter lacing. It has metal grommets, which should prove stronger than the grommets on the U-N. But I can't see myself playing more than an hour on a hard courts in this shoe, maybe 2 hours on clay. The Pro C is more fashionable than the Ultra-Natural, but not as "cushiony" - the ladies on my tennis teams will be disappointed. 3.5 - play 3-4x week - hard and soft courts.
