Tried it on in-store and the display model fit a bit oversized, which I was looking for. They swapped it out for a package at point of sale and this one fits a bit tighter and is shorter. Still okay, but I may have bought XL if I knew.
Super light. Very comfortable. Fit well. I'm an 11/11.5 in US sizes and size 44 fit me well, but might a bit tight if your feet are closer to 11.5.
