This collection contains 10,000 varieties of foot coverings and, through the changing fashions, highlights the craft and sociology of making shoes. Some items date back more than 4,000 years. Pressurized sky-diving boots, iron-spiked shoes used for crushing chestnuts, and smugglers' clogs are among the items on display. Elton John's boots have proved wildly popular, but Napoléon's socks give them a run for the money. COST: $6; free first Tues. of every month.
