I have only had my yaktrax walkers for 2 weeks so I cannot talk about their durability. It has though, been two weeks of the toughest November weather in Ireland for decades. In these two weeks I have worn the Yaktrax in snow; in refrozen snow and compacted ice; and in defrosting slush. I am almost phobic about walking in slippy conditions. For the most part I feel these Yaktraxs have helped me regain my confidence in walking in slippy weather (and therefore reclaimed the winter for me). They have worked well with compacted snow and ice, and with defrosting slush (the latter which had others hanging desperately on to railings etc as they walked along). Where they weren't so good for me was where compacted snow and ice refroze hard over some of the very low temperature nights here. In these conditions I felt that the Yaktrax couldn't get the same grip as spiky ice cleats would have. Instead they slid a bit over the (very hard) surface. Saying that, even if their longevity is short, I'd buy them again. Its cheaper than broken bones or loosing my independance.
