Abstract
An apparatus for measuring volume of a lower extremity includes a substantially elastic sock body with a leg end, a toe end, and a length between the leg end and the toe end. The sock body may be dimensioned to substantially snugly receive a lower extremity. A measurement thread is attached to the sock body in a manner that causes the measurement thread to wrap around the lower extremity in multiple coils along the length of the sock body. The apparatus also includes a measurement gauge that measures at least one attribute of the measurement thread that corresponds to sock volume. In one embodiment, the measurement thread is substantially inelastic and has a fixed end, and the measurement gauge measures length of the measurement thread between the fixed end and the measurement gauge. Other embodiments are described and claimed.
