I was pleased and surprised that these Kamik boots (Canadian company, but apparently the boots are made in the U.S.) stick to snow in a way that means something to me, living at nearly 10,000 ft. in Telluride, Colorado.  I was replacing Sorels, which I liked, but these stick better to snow, really, in a way that significantly reduces slipping while walking or casually hiking about in winter.  This effect was obvious from the first wearing, and I presume is attributable to the compound of rubber or other material used for the sole.  Whatever it is -- works like a charm!

Note: These boots were much lighter than the ones I was used to, but still keep me warm, no worries.  Highly recommend.
