Come on Vibram, they don't even come close to the advertised size compared to other shoes in the same size. I have 4 other pairs of Vibrams in size 47 and while I would like to see a size 48 I can get them to work on my size 13'. I couldn't even get these Trek Ascent size 47 cushioned shoes on my feet. Shoe sizes are obviously based on the size of the foot, but it's like Vibram removed the size with insulation instead of creating insulation from the size. Since 47 is the largest size Vibram makes for some odd reason, I think I'm SOL.
