YakTrax Chains Winter Traction Device, Men's 9-11

We had heavy rain flash freeze overnight. Everything was covered in 1 inch of solid ice. Rock salt was sold out. It was dangerous to take even a single step outside. These chains fit over the soles of your hiking/snow boots. They don't move around. They give you enough traction to get outside and get the mail or scrape the car off. Especially good for middle-aged people who are a little shaky on ice because their knees are starting to go. You don't need them often but when you do, there is no substitute.
