Well I only said that they *look* less durable. The uppers appear to be constructed out of perforated sheet material with no hint of any fibre inclusion as opposed to the more normal woven materials used. They look to me like they could tear easily or suffer fatigue cracking.

As I say, that just my opinion based on how they look. Be interesting to read accounts of how well they last in practice.
