They are a little snug pulling over size 49EU wide bike shoes which is to be expected. My only ding against these is that the top velcro strap that closes them above the ankles is too narrow and can cause some rubbing if I'm not careful in how I affix the closure. They are made for skinny legs. Otherwise they keep my feet dry and warmer on those winter rides.
Great covers. No water penetration. Zippers are great.
