I'm surprised to be writing this review. I've been wearing Keen products for 10 years, and I've loved every pair. These boots, however, are a total miss. I wore them today for the first time in the snow, shoveling for about 45 minutes and then my commute to the city. My feet were just as cold in these boots as they are in my non insulated Keen hikers. And my feet stayed cold for hours after I was indoors. I had to take them off to warm up. And there is also some kind of ball in the heel of the boots, and on my commute home right now, my heels and ankles are killing me. The boot is kind of useless, and I seriously regret buying them. I love Keens dearly, but these boots are pretty bad. I've worn them outside, so I can't return them to the store I ordered from, and I don't think I want to put them on again.
