text: Very happy with this shoe.  Lightweight & flexible; comfortable while running. Shoe fits a bit snug out of the box; this style seems to run small. It has been my experience that there is a noticeable size difference between various shoe styles with Vibram. A 40 in one style does not necessarily translate to a 40 in another style. This makes purchasing this manufacturers shoes online difficult. Overall, I'm still happy with my purchase.
