Thigh-high boots

Thigh-high boots, known also as thigh-length boots or simply thigh boots, are boots that extend above the knees. Other terms for this footwear include over-the-knee boots (abbreviated OTK boots; the full term is also used for the 15th century riding boots for men, later adopted by women) and, especially when cuffed, pirate boots. Lengths vary from reaching just over the knee to reaching almost to the crotch (referred to as crotch boots or crotch-high boots).
