Hello. I have a problem with tremendous wear on my Asiscs shoes in the heel area. I am a recreational player and play about 3 times a week and my clay court shoes have been played about 3-4 months now. However, in the heel area, the material has already worn down to the plastic. This wear is inexplicable to me. Some of my tennis partners also have Asics shoes and this problem does not occur. Does anyone know the problem? Who can help?
