I'd seen the original Yaktrax worn by someone in the ice last year and thought they looked like a great idea, as in the past I've suffered two broken wrists and a broken knee from slipping over.
Unfortunately Yaktrax had sold out by the time I found out about them, but I managed to get hold of a pair of these before the cold weather arrived, and got some for my parents at the same time. They do work, after a fashion, but the problem is that as soon as you have any lateral or rotating movement (ie turning around) they just fall off and sometimes it's a while before you notice they've gone. This got so frustrating that on the second day I wore them I got on Amazon as soon as I got home and splashed out on some Yaktrax Pros. Have to say I'm glad I did it - glacial conditions this morning, have just done the mile and a half round trip walking my kids to school on pavements which Torville and Dean would enjoy more than me, and didn't slide once. And, more to the point, the Yaktrax Pros stayed on my feet even without the straps on!
Have just ordered my folks the Yaktrax Pros as well. They are in their 70s and Dad was tying his Snow Trax on with shoelaces as they did exactly the same to him as they had to me.
So, don't spend the extra on these because they definitely aren't better - save a bit of cash and get the proper Yaktrax instead.
I've only given these one star because I can't give none at all!
