I need to buy some actual tennis shoes as my Mizuno running shoes have almost caused considerable injury a couple of times.... I'm a moderately skilled player, but fast. I held a couple of sprinting records at my high school and still move well at 31. I need something that will provide ankle support, but won't slow me down. Also, I have a high arch in my feet and need some support there (I can take care of that with an insert though). As far as durability goes, I play 3-5 sets each week. If you have any suggestions, I would greatly appreciate the advice. Thanks!
