I had purchased a pair of Yaktrax Pro a while back for running in snow. I used them occasionally, but discovered that they work best on packed powder conditions and aren't that great on ice. After a few months, they broke. One of the rubber sections inside the metal coil snapped and they were useless then.
I checked the Yaktrax website and submitted an online query and they replied that they would replace them!
When a successful company stands behind their product, I commend them for it. There are so many examples of bad customer support that it's refreshing to see a company willing to keep their customers happy.
These bad boys will be seeing many more miles on the trails.
Thank you Yaktrax!
