"Winter is coming...!!! My husband needed another pair of boots and lucked out with these. The size runs true for him. I noticed that one of the reviews stated that they were narrow which was not true for him . He has a wider foot and these fit perfectly so they might actually run a little wider than normal. The zipper (his first boot with a zipper) makes throwing them on quick and easy and the gray is a nice neutral. He's worn these probably 6 times in the past few weeks and they have successfully weathered a few wet and sloppy days. My plan is to go back and get him a pair of the brown but I love the gray with khakis and jeans. Oh yeah...I'm not sure that they are designed for warmth...but he says that they are all he needs when heading to work in his professional casual wardrobe."
