My feet are always freezing in the winter and I have invested good money in boots to avoid frozen toes whilst hiking or winter sports, with no luck!
Until I found these. I just ordered my second pair. These are amazing. They are rugged. They are pretty stiff, but I appreciate that sort of fit/support in the snow or on ice. Most importantly, my feet do not get wet or cold. At all. They don't overheat, either.
As far as the fit, I usually wear a 9, bought these in a 9, and i can wear comfortably with thick hiking socks. I highly recommend!

Excellent quality, well fitting and comfortable all day long even in wet or snowy conditions.

It was fine for a few months, but the metal parts came out of the boot fairly quickly, which completely negated the ability to lace them up all the way and have any ankle support.

These have the best trend of any winter boot I have ever had! I had no fear of walking on icy ground in these boots. That is saying a lot as I live in Northern Wisconsin! Also they truly keep your feet warm in below zero weather. They are a bit stiff at first, but improve with wear. Highly recommend!

I have bought at least 3 pairs of boots this year. As a mail carrier the below 0 temps have been brutal this year! I finally found my ultimate pair from Keen! No Cold or wet feet anymore! Thank you!

Perfect for Winter Hikes - Toasty Toes: I got these for winter hiking. After it snowed 12", they did well walking around town. My feet were warm and strayed dry walking through slush. I even went on a winter hike in the mountains and they had great traction on snow & ice. They come with a warm insole on the bottom, but I had to add an additional insole for cushion & support. Overall, plesantly surprized by these boots & would recommend. I'm super excited to use these for future winter adventure!

Worked in these shoes for over a year. No complaints, they saved me from many ankle rolls walking many miles delivering packages.
