I compared the waterproof version of this to this actual boot. I have wide feet and this version fit so much better. I got a size up for each. These boots were spot on from the get go. Very easy to put on and the zip is a boon. My first trip out in them was initially when the ice warning came on 4 degrees C! I needn’t of worried as they were not cold and kept my feet warm enough until the temp increased. 5 stars in every department for me ?
