I usually wear a men's 10-1/2 D closed shoe and a 10 in open
sandals. The Euro size 44
Mephisto Norman I purchased is supposed to be a 10, but it is unusually large and it feels more like an 11-1/2 or larger. I have been wearing them barefoot, but I think I will be adding
socks soon, since the leather remains a bit hard and is not softening up. The width feels more normal, although I have both straps buckled on the last holes. I did not return them for a size exchange because I started wearing them, hoping to get used to them. On the plus side, the back leg of my
jeans doesn't get pulled under my heel anymore apparently due to the extra length in back of the
sandal.
