I bought these to replace my old purple 100% Mohair skins that lost there uphill grip. While the new orange skins grip way better than the older style ever did, they don't glide at all! Places where I would typicaly have to traverse I am now just bombing straight up hill! I can't belive the grip these things have! Everyone else I BC can't follow my uphill tracks. However on long slogs out I have to work way harder now. The old purple skins would glide in almost any snow condition, these new ones hardly glide down hill. The stickem is way tackier than the old style... Cheat sheets are a must and I never have had the tail come off my boards, big plus there. Bottom line is these things are the best for climbing, way more durable and longer lasting than the older style skins, but the cost for this is limited glide.
