Yaktrax are not new but, whenever I use them, others want to know what they are and how to get them. Given the current weather pattern in the northeast and the fact that many of us won't see ground again for months, it is time to list them as one of those design solutions that are a must have. Out of the box they are a mystery.
You stretch them onto your boots or shoes and they add grippers that prevent slipping on ice. Once you reach your destination - the car, the subway or work - they slip off and fit in your pocket.
Yaktrax are conveniently available from Amazon.
