A court shoe (British English), or pump (American English), is a shoe with a low-cut front, the vamp, and without a fastening. They are usually worn by women, but are still traditional menswear in some formal situations, where the style is sometimes called an opera slipper or patent pump. Pumps with a strap across the instep are called Mary Janes. Pumps may have an ankle strap.
