Garnet Hill makes these adorable boiled wool slippers. They each retail for $44, but are on sale now for $33. And, there's a free shipping promotion for the holidays. And, I'm pretty sure if you search around the internet you could find yourself a coupon code for an even deeper discount (if you do share the wealth in a comment). Sizes start at toddler (4-8) and go up to kids (1-3). My favorites are the monster and the shark.
