Good material and protects from the cold at temperatures in the upper 30s and low 40s. Tight fit and not the easiest to put on.

Although not the sleekest covers the are easy to put on and take off and seem warm.

Almost toasty.

They are warm!

After receiving these show covers, I decided to buy dedicated warm (mountain) biking boots instead. The boots are 2 x more expensive, but keep the feet very warm, and are more rugged for when you need to walk or run. The shoe covers themselves are good quality and seem fine for what they are.
