I had as a precaution, ordered larger due to the reviews, even a number to me. But that would not have been necessary. On my Sidi race shoes in size 42 fits the Gr. 41/42 super. That's what I have to complain about, and therefore only 4 stars, they are pretty close up at the leg ends for me. They get too heavy. The additional Velcro is great. Have they been tested only once. Therefore can not say much for durability. The clicks are the way to use easily. You have under the rubber a light fleece layer to keep the wind from good, but wife gets at about 0 degrees still cold feet. But there are also no winter overshoes. How waterproof they are I do not know, the dirt from the shoes they definitely keep well from :-)
