I'm a huge fan of vibram fivefingers and attribute my daily use of these shoes for my strong and pain free feet....that being said, this style does not measure up to reputation.<br />First, the sole feels more rigid than my Bikila and my original KSO treks.<br />Second, the stitching  seems run directly down the center of the inside sole, creating rubbing and blisters.<br />Third, the heel cup comes to a point at your Achilles tendon and combined with that aforementioned seem, scratches and bruises the back of your ankle during normal walking with an increasing annoyance and pain during running.<br />However, these are insulated and water proof enough for me to keep warm and dry feet during work at my job in a meat locker.<br />I'm experimenting with using sports tape for my ankles and the injinji socks help the soles of my feet from getting scratched by the inside seem. I bought these from the Vibram's store website not this seller.
