Best winter boots

Great experience with these boots this winter. The material has some stretch making them easy to get on, but keeps the fit really snug. Always looking for the boot with the tightest fit and eliminates any room for water to sit around. I am impressed with the fit and warmth. Lots of days with water in the low 40's this winter and these 5mm boots were great. Highly recommend.
