I bought these for my son who thought they looked really cool. The idea was to use them primarily as water shoes for swimming, etc. and also casual as needed. They turned out to be extremely uncomfortable in the achiles/ankle area. Tried using bandages and other adhesives, but none adhered to the material long enough to alleviate all day use or even a few hours.  We ended up using only when he was in the pool, otherwise too uncomfortable. It's a bummer because the concept is great, and the shoes were really expensive, but not worth it.
