Buskin

Chambers's Encyclopaedia, Volume 2: Beaugency to Cataract, p. 580

Buskin, a kind of half-boot lacing tight to the leg. The ancient tragedians wore buskins (cothurni), often with thick soles in order to add to the actor's height. Hence the 'buskin' is often used for tragedy as 'the sock' (soccus, 'a flat-soled shoe') is for comedy.
