I have been using indoor soccer shoes to play tennis. Although they fit my feet well and I don't have any pain when using them, they have traction and durability issues on a tennis court. I have wide, flat feet (a ski boot fitter in Aspen told me I had the widest, flattest feet he had ever seen), but my main issue is when I started buying tennis shoes is the raised heel. For me, it causes heel slippage as well as leg, ankle and back pain. I've tried different insoles without much success (and most quality insoles have a raised heel as well, so it doubles the issue). The two main shoes I've tried to far are the Asics Gel Game and the Lotto Vector (also tried my friend's Propulses without success). The Asics were better than the Lottos, especially when I changed insoles (although I still had pain), but the Lottos were bad for me no matter what insoles I used. I actually played with them without any insoles, and it helped a lot, but not using insoles really messed up my feet. Are there shoes that have very little difference between the toe and heel? Some of the Nike shoes look like they have a smaller difference between the heel, but I don't want to keep spending money trying to find the right shoe. I'd prefer not going back to the soccer shoes, but it might be my only option.
