This was just what i was looking for to get started with "barefoot" running. I use them sock-less, and they are pretty comfortable. I got these as an alternative to the Vibram Five Toe shoes, which were just too far out there for me. These have the same Vibram made bottoms, but with a more conventional top. I would recommend going on very short runs at first to warm up to the new way of running. I went on a mile run my first time out, and my calves were hurting for a few days after. Afterward I read that for a conventional heel to toe runner like myself to transition to toe to heel running, you should slow your way into it.
