Red thighboots with stiletto heels
A thighboot is a boot that is so long that it covers part of the thigh. Such boots are staples of fetish clothing, and are often regarded as a necessary accompaniment of a catsuit.
Thighboots are normally made so that the part at and above the knee has no back or at least is quite loose, allowing the wearer to bend his or her knee easily. However, they may be made deliberately tight at the top so as to restrict bending of the knee.
Usually, such boots have long zips to allow them to be put on or taken off easily. They may also have lacing; this may be purely ornamental, or it may allow the boots to be tightened, especially if the intention is to stop the knee bending.
