These are very well made boots! This is my second season and they show virtually no signs of wear. I backcountry snowmobile at !0,000 ft. and need the protection from the elements. They are waterproof and very warm. I always buy KLIM gear but went out on a limb and bought these and must say I'm pretty impressed. Especially considering the starting price point on comparable KLIM boots is over $100 more. BUY THESE BOOTS! You'll be glad you did!
