David S.wrote a review of Mavic Crossmax Thermo Shoe Covers on November 23, 2018
Familiarity: I've used it once or twice and have initial impressions
These shoe covers fit poorly and provide no insulation. They provide little coverage of the actual shoe. I wore them on a mild day by Minnesota standards (40 degrees), and I could feel the wind and cold going right through them. I wish I had never worn them so that I could return them!
