I have been riding for several years and winter riding has always been a challenge. But after trying unsuccessfully to get a pair of shoe covers to transform my summer shoes into winter shoes and never finding more that flimsy toe covers in my size, I broke down and ordered these. What a difference! I suffer from poor circulation in my feet anyway so these are just fantastic. Only my first ride today but they worked so well I wanted to get the review in right away for others who are looking for warm feet on winter rides. I've had my other pair of Shimano shoes for years and they are still very comfortable and holding up nicely.
