I had a pair of the Ariats for last Winter. I do believe they were a pair from their H20 line. Thinsulate insulation and supposedly waterproof. They were black leather and ankle high (not great for deep snow). I only had use of them one Winter season. The zipper broke in both and cost me $40 to have 2 zippers replaced (repair shop didn't have as fine a tooth zipper style for the replacement, so after that boots leaked through the zippers). They might have been under warranty wtill, but I couldn't take the time to send them away and see what manufacturer said about them... needed boots to wear, so I had fixed at local shoe repair shop. Now I'm leery of buying another zipper up style boot. Then the leather cracked across the top, in the area above the ball of the foot so of course my feet started getting wet, so they went in the trash.
