I gave this product 5 stars because the comfort, the fit, and the cost was great. I had Naturalizers before its why I bought them in the first place. I have big calf's they are about 18 inches and the boots fit great. To anyone that has big calf's as I do you should buy the boots about a half or a hole size bigger then your shoe size. The boots were shipped out on time and I got them within the time it said I would.
