I love these but I will say if you have a larger foot they may not work for you.  I wear a size 6 1/2 (size 38 in Vibram) and they fit me great but I know if my foot was any larger they would be too snug. They are pushing the bounds so to speak, like snug on me yet still feel great, but bigger may not work.  They truly are no show in my vibram alitza so they were a great buy at a good price.
