I've had yaktrax for years and they've always held up at least one possibly two Winters. However I bought these Pros for my husband and after one wearing the rubber has snapped underneath of the springs. The black rubber on these ones seems very weak compared to the rubber on the clear ones I had purchased years ago. Since I bought these two years ago and this is the first time my husband has wore them I'm out the $21 that I paid for them and he's only wore them once I will never purchase them again I'm not sure why they changed them but they need to get back to their quality product
