The right shoe was tighter than the left.  Placed side by side the right is smaller, and regardless of which foot I place in the shoes, the right is tighter for both the left and right foot. Thus, quality control is not good. I wear a size 10.5 US, and received a size 11 which would be too small if I wore a wintertime sock. Even for summer weight socks the shoes are tight. Would only purchase if you have narrow feet and if so, get a larger size if you plan on wearing heavy socks while driving.
