Well I bought this new pair of Wilson tennis shoes last year, and for the first 6 month it felt like a pair of industructable feet torturing device. My toes usually hurt and my big toenail is usually destroyed after an hour or two of playing. Since I am completely broke I just kept wearing that pair of shoes... and just when they start to feel comfortable, the top part of my left shoe started to tear up. There's a big hole on the top fabric. I was wondering how many of you play with broken shoes and at what point should I replace them? It's too bad coz that pair is very comfortable to wear now... I even move so well wearing them.
