Wow. After seasons and seasons of shoe covers ripping or pulling up over my toes after hike-a-bike situations, I finally found a pair that truly do what they're advertised to do â€” keep my feet dry and warm. One word of caution would be to size up because the rubber toe makes it difficult to pull the cover fully over the shoe. The zipper also can be difficult to fully close if the covers are too small. I wear a size 46 in Shimano, and I had to get the XL size. They fit perfectly.
