The boot is very warm, and effectively repels water, but it's so uncomfortable to wear that after trying several times, I had to give up.
The upper part of the shaft has no give at all, and when you walk it digs into the back of your leg. Even after several days of working that part of the boot to try to get it to soften, there was no luck.
Also, the top of the boot is too narrow to accommodate your pants leg, so you end up not being able to tuck them in- which defeats the purpose of being waterproof since your pants are not protected by the boot. Columbia is such a great brand, but this boot is a major disappointment.
