I love the Merrell barefoot concept so much that we have five pairs of various styles in our two-person household. When I saw these, I planned to rock them teaching Zumba. Sadly, after several wearings, each less comfortable than the previous, they had to be returned. The soles on this model, as well as the toe caps, are quite rigid, not allowing full 'barefoot' feel. They also are just a skosh too small in the length, and sizing up a half-size was way too big. So, buy for style, but not for intense activity.
