I own three pairs of them (2 are lace up and one is the new slip on style) -- my family members also each have a pair. I really like them. They're extremely lightweight and comfortable, even without socks. As they are fabric (wool), they aren't at all waterproof or water resistant. I generally take them as my second pair of shoes on trips when I know I'll be doing a lot of walking (my first pair being something a little more rugged and water resistant, like a comfortable pair of ankle boots).
