I wore these quite a lot on an adventure vacation - and I even purposely stepped in puddles (less than ankle high, anyway) to test out their waterproof abilities. Well, I'm pleased to say they kept my feet dry, and were able to take on a lot of terrain in temperate climates.

The only detractor is I definitely have to wear blister band aids on my heels, as the way these come up rubs the wrong way.

If you're looking for cold weather shoes, these are not your answer, but Columbia makes excellent boots with cold ratings. I have another pair for just that, and those are great, too.
