Trail Running Gaiters
If you're going to be running or hiking in the woods in the Winter, you need to wear something to keep rocks, sticks, splashes of water, and snow out of your shoes. These REI Trail Running Gaiters ($30) are great to slip on on days when wearing snowpants would be too hot. They fit over your footwear and workout pants, keeping you dry and protected. The stretchy fabric helps them stay snug around your lower leg and the reflective strips on the back increase your visibility. Not exactly glamorous, but definitely necessary if you run in the snow.
