This is a minimalist shoe with a unique design that follows the shape of the human feet. The toe box is not rounded but has a unique shape giving toes the ability and comfort to land in their natural position. The shoes is fairly bare with a sole and somewhat of a mid sole that provides some cushion but minimally so (of course). But this shoes does take time to get used to and requires incremental use by those not used to a minimalist shoe. Minimalist shoes are not for everyone but this shoe is a strong possibility for those who want a step up from the 5 fingers vibram and it has a virtual zero drop between heel and ball of the foot. The shoes are also well ventilated. As a masters runner, I venture in these shoes carefully and try to wear them at least once a week, I do add a different insole for support.
