Vibram Fivefingers Women's VI-B Shoes

In the Entrada, I bought a size 40, and that fit me best. All my toes were able to extend comfortably in each toe socket. That's critical. I got my Vibram Entradas from Zappos, and tried both a 39 and a 40 before determining he 40 was my true size in that model. The sizing chart here at Swimoutlet for the VI-B's was really different from my past experience. I am a true blue size 8. In ten years plus I have never bought a larger size or smaller size than an 8, when buying in U.S. women's sizing. Buy Euro sizing is a different matter. But even so, Swimoutlet's sizing for Vibram VI-B's is way off. According to their chart I should have bought a size 38. I thought I was safe to buy 39, and assumed this Vibram model was different in sizing than my old tried and true Entradas. But alas, the 39 scrunches my baby toe and my big toe is right up against the top of that socket and would grow irritating quickly too. Unfortunately my size, a 40, is not available for now, and when it is, it will be for almost at much as what I can get it for at Zappos, without any guarantee for free return shipping just in case, in this style, I need a size 41. Mind you, if I got 41, because the 40 was still too snug, according to Swimoutlet, that would be a woman size 11. Crazy sizing. I don't know how the only other reviewer could say the fit is true to size. I'd use a different shoe seller's tables for determining your size and then come back and get your correct size, if it's available.
