Title: Excellent for subzero biking
Review: I give props out to whoever invented these things. Excellent stuff! I've been biking the entire winter (about 20 miles per day) here in Chicago and I have been wearing them over my Texas Steel boots. Last week I tested them for a 45-minute ride, with a negative two degree temperature (and -20 to -30 degree wind chill), and with only wearing white socks plus and extra pair of thick hunting socks, the boot covers did the trick and kept the toes at a normal temp. The only suggestion I would give is for the inventors to reinforce the elastic band that holds the front part on as it is starting to wear away and I doubt I'll get a full two winters out of them.
