A hose (plural “hosen”) is a close-fitting piece of clothing, covering the leg from the thigh to the sole. It’s a period charge, both when worn on a leg or in its own right; an example of the latter is found in the canting arms of Hose or Hoese, c.1275 [ANA2 550].
Society armory also has examples of the “sock”, intended to cover only the foot no highter than mid-calf. Though a period article of clothing, we have no examples of socks in period armory. Hosen and socks have their openings to chief by default. See also shoe.
