Vibram FiveFingers minimal toe shoes. From the photos, you can see these are the "SmartWool Next To Skin," with a gray fabric upper and yellow Vibram logos. Elastic toggle closure at heel. Flexible barefoot-style sole. These are European size 45, which translates to US size 11. I have several pairs of these, and also do some light running with five fingers. These are barely worn, as you can tell from the soles. One photo shows the gray wool upper, where the Smart wool has a tiny opening at the toe. I ordered these from a local shoe store and I believe they came with the separation at the toe. Apparently, five-finger shoes are known for that sort of thing. The smart wool interior is very comfortable, and the size 11 IS an accurate fit.
