I had originally given this item five stars for comfort and the way they look, and this after a mile-long walk with the dog at the first low temperature here in Atlanta in order to test them out. I bought them in the Fall, intending to wear them for a Christmas vacation in snowy New Mexico. After my first day of wear on the trip, the backs of my ankles were chafed and red. I was wearing cotton gym socks under them. No lacing combination relieved the rubbing. The next day, I wore some cotton boot socks over the lower legs of poly thermal underwear, hoping that I could comfort my ankles. NOPE. By the end of two days, dozens of red sores covered the backs of my ankles. I wrote the company and they said that they hadn't heard of this (essentially discounting my comment). But another Amazon reviewer has written about the same identical problem. Columbia said to send them back under their warranty so they could "inspect" them, but I'm sure going down that road will only cost me more since there appears to be no damage to the boot. Money down the drain.
