This Spiked Rubber Band Equips Any Shoe for Icy WeatherS

If you don't want to spend the entire winter wearing clunky boots, these elastic Nordic Grip Mini straps feature a pair of metal spikes that give any pair of shoes enough grip to tackle snow and ice. Strapping them on is as easy as putting an elastic band around your wrist, and they're available in three colors for just $15 a pair.

You're probably not going to want to tackle Everest wearing them on your favorite pair of Vans, but the Nordic Grip Minis are easy to carry around in your coat pocket as a backup should the weather suddenly turn slick outside. [Firebox]
