These are a great pair of boot insoles, with nice, warm faux wool for softness and warmth, then a shiny foil-like layer on the bottom to reflect warmth back to your feet rather than out through the bottoms of your boots. They're nice and comfy and easy to size. They come with a cardboard template for all the various men's and women's sizes. I'd recommend them if you want warm, comfy feet this winter!
