I just came across these Pedisavers pedicure socks ($16–$20), and I can't stop giggling. The idea is that you put them on before applying polish, so that you keep your legs and feet warm. Additionally, these socks eliminate the need for toe separators. (Are toe separators a big problem that needed to be solved?) I doubt I'd wear these, but for cold-footed pedicure addicts, maybe it's a must-have. What do you think?
