What's the difference between footless tights and leggings? Well, footless tights are just like any other pair of opaque tights -- they simply stop at the ankle. Just the right weight to keep your girl warm without adding the thickness or pants-like bulkiness of leggings, footless tights add that splash of color to dresses and skirts while letting feet wiggle free in flats, sandals, or socks and sneakers. Reinforced gusset, waistband and seam are designed to withstand constant wears and washings.
