I was noticing that every time I wore my insulated duck boots, my hip started hurting. I looked at them, and realized the narrow heel and tight toes were making me change my stride. So, I looked at some different barefoot brands to try and find a flatter, warm winter boot. This one has worked great for walking in snow, going sledding, and does decently well on ice. They are nice and warm. I've worn them in high teens with a medium weight wool sock, and my feet have been toasty! The waterproofing is holding up fine, but I've only had these for a month. I've worn them almost every day, though! They are very flat, but comfy. They do run a little narrow, but fit my foot well. I normally wear a 9 in boots, but had to order a 10.5 in this brand! So, if you are a lady with a larger foot, you might need to order the men's in this style. Overall, I'm very happy with these! Kind of feels like going out to play in the snow in comfy, secure slippers! I have large, painful bunions on my feet that require me to wear flatter shoes (I'm only 31, but have been this way forever), and these allowed room for my bunion with no straps or pressure going over that area.
