I bought these boots in brown in 2019. I have a bit of raynaud's syndrome so my feet always cold in winter and are only warm in summer. I have tried many, many boots and shoes, as well as shearling foot beds, to keep my feet warm during New England winters and ski trips where the temps are often single digits/low teens after skiing and at night. I also have a very narrow foot so am usually only good with lace-ups. These boots are fantastic! Not only do they keep my feet warm, but they are very comfortable for long winter walks.. They have good grip on icy paths as well. Just ordered my second pair in black - I've been hesitating for 2 years and couldn't do it any longer. Great with jeans, leggings, skirts. They are my go-to winter shoe.
