SALEM, Mass. — Fetishists, historians, collectors, sneaker freaks — there’s something for everyone in the new show “Shoes: Pleasure and Pain” exhibit, which runs from Saturday to March 12 at the Peabody Essex Museum here. The show features more than 300 pairs, ranging from leather “duckbills” (1520-1540) worn by fashionable, pre-Elizabethan gents to a pair of 3-D-printed, carbon fiber Julian Hakes heels (2014).
