I recently have been using these shoes strictly in a gym setting for 3 months. This week a hear a clicking type noise while walking. I notice on both shoes the tread is failing at the exact same point. Where a hardened design on the outer side meets the tread, the tread has broken off. Calling Adidas was no help. They claim this is normal wear and tear and not a design flaw. So if you expect more from a gym only shoe don't buy these. Other than that, comfortable shoe. And customer care is not helpful.

Absolute bargain very comfortable for not a lot of money highly recommend
