They are wonderful. I ordered two pair to try them out and enjoyed them so much I oredered two more pair. They fit well and are warm. Of course, you need an extra shoe 1/2 size for the perfect fit.
They look good and feel good when new but I can't seem to get more than 3-4 days use out of them without having them wear through the bottoms. Have tried two different sizes over the years just in case the smaller size is being stretched too much causing the premature wear but get the same results even with the larger size. They seem to be knit loosely and maybe that has something to do with them quickly becoming thin on high stress areas.
