After using them 4 months: definitely one of top shoes you can get for indoor game like TT. Excellent grip on wide range of floor surfaces, feels light and gives you confidence in all positions. After playing ~6h a week for 4 months it has no visible damage so durability is OK so far. The only negative I can say (beside design which is subjective but I still like Wave Drive 8 and some from Crossmatch series more then WD7) is that I feel not 100% naturally when I take the shoes on, like deficit of support in the middle of the foot. But this disappears few minutes after I start playing and then during the rally I just feel confidence from my moves.
