They claim on their sizing is that a european 41 is equal to a woman's 10 1/2 to an 11. This is inaccurate, as you can see on any conversion chart on the internet. A 41 is a woman's 9 1/2 - 10. So no matter what, your shoe will be a full size too small. Go check out any conversion chart and order according to the real size you need.
