Here's the slippers with my foot for comparison. Don't you love the socks? I do. Bright blue and green argyle knee highs. Score! Actually, it's because I don't wear longjohns unless I have to, since I have a very short rise. This means that the longjohns come up to my ribs and show above my jeans. Hence I wear knee-highs for warmth, unless it's below -30. Then I wear longjohns. I'm only so brave.
