"Ultimate non-skid" as per a comment from a passer by at the trail head of our 12 mile trek. They worked perfectly for the conditions we were in (iced over snow) at San Jacinto Mtn C.A.. My girlfriend wore these and did not slip once but did tear a hole in her pants. They fit her great, were not too tight, and were very easy to take on and off. Would definitely buy a second pair as long as these ones last a respectable period of time.
