Adidas Taekwondo shoes are great and look good to. Dont want to sound like a self promotor or spam but ..... they have sole supports and pivot points on heel and ball fo the foot. If its like the the ones over here tennis courts are fairly abrasive to all shoes. The Adidas are about £68 though. If it was me I would just buy cheapest Taekwondo shoes out there as although adidas may last longer and have comfort in the long run you may be cheaper buying new cheap shoes every couple of months ?
