Such a simple idea, used them twice properly. The first experience I had with them was walking up to the saddle between Donard and Commeda in the Mourne Mountains. there had been heavy snow, and the steps on the way up from the valley to the wall was pure ice, lethal. threw on the yaktrax and couldn't believe the grip they gave to my boots, superb. The next experience i had was when we went skiing to livingio in italy, the main street was never salted, so was like an ice rink, used them pretty much everyday once we came of the slopes
