Keeping my feet and ankles warm in the snow! Soft and comfy. Don't need to zip or unzip to get in and get out. So I do wish that it was a little less wide above my ankle. My foot stays in great while I walk. However, if I don't have a pant that goes over the boot, snow gets in to the back of my ankle. On the other hand, the boot was so warm, I didn't notice snow was back there until I looked ;-) The size 11, my regular shoe & Keen size, fits just fine. My toes are at the top, but are comfortably up there. The tread makes for great slick snow walking.
