Looks to be a very nice product. I have only used them 4 times so far but seem to be much better made than others I use from name brand companies. I bought the XL size for my size 45 Shimano MTB shoes and they fit perfectly, easy on and off. Zipper works great and they really have kept my feet dry in a few good downpours. It has only dropped down to about 42f so not sure how they will bear up when it drops down into the 20´s & 30´s for warmth, but they also seem to be very good at keeping wind out as well so I am optimistic. Good find at a perfect time of year for me.
