I rode with these on last week for my rainy century ride and yesterday on a morning downpour. As a previous reviewer said, they do fit tight, but that's what one would expect and want to keep the rain out. You have to keep in mind that this is a waterproof product, so it should fit tighter. I wear a size 45 (about size 11) Diadora road shoe and the XXL fit great. After my rides, my shoes and socks were bone dry. I bought these mainly because of the trusty Gore-Tex lining and it performed great. Zipped all the way up, the ankle is tight but I found it gave a little after my rides. Because of the ankle tightness, the rain that dripped/ran down my legs did not penetrate in. These booties are snugger than my Sportful Windstopper ones, which I also love. Overall, I very good waterproof product.
