At 68 years old, Ihave never hav vibran 1/2 soles, and have never experienced that problem. I have worn holes through the outer soles. For some of us who live and work on carpeted floors vibram soles are not all that good, they can catch and trip you up where a leather sole will slide a bit. I also prefer a leather sole when I hit a wet vinyl type floor, it grips better there and does not tend to slip like a rubber sole.
Well Jeff, you and I are about the same age but the big difference is you work and walk mostly on carpets and I would agree the vibram is difficult. I have had many pairs of leather soled shoes over my lifetime (some more expensive and better made than AE) and have worn holes through the vibram and sole. Having said that, I get to a point with my all leather shoes that they become like slippers and I would dread losing them. Shoes have a finite life. The vibram gives me many many years out of them.
