Very comfortable and warm, I've walked at least a mile a day in these (just back and forth indoors) and feet felt fine at the end of the day. I actually got them because I wanted a warm over-the-knee boot to wear at work, where the a/c is blasting even in the dead of winter, and received many compliments on them, and coworkers even asked where I got them/what brand they are. They have become a little more 'slouchy' after wearing them over the last few months, but still very comfortable and cute. I don't know how/if they'll hold up over the next few years, but for this price, you can't go wrong. I'm a very satisfied customer.
