In reply to Removed User:
Some Vibram soles are really good, others are pretty rubbish — they must make hundreds of different versions, some to specifications from boot makers with funny ideas of what users are looking for. The name alone doesn't guarantee quality, and some own brand sole units are just as good (again there are also really bad ones about).
I never liked the rounded heels, which seemed to me to result in unnecessary slips and additional erosion.
