The shoe itself weighs practically nothing, and is quite airy. How the shoe expect from a Natural Running, the sole is extremely flexible, I think that this is achieved by the spherical bottom structure. It's actually almost as if you walk barefoot. As a particularly noisy I have not felt the shoe, trail shoe as he is probably not to see more. They are somewhat more stable generally.
The design also like it very much, the photos do with the actual color match.
The only shortcoming: Without socks it feels inside but somewhat scratchy, and probably would quickly lead to sore feet (may be interesting for triathletes). Since I am personally but rarely without socks go, there's me 5 stars.
