A type of short nail with a large head, used to reinforce and protect the soles of shoes or boots.

Hobnail → The word is formed from "hob" (from Middle English *hobbe*, meaning a small, stout man or a term of endearment) and "nail" (from Old English *nægel*, meaning a metal fastener). A hobnail is a type of nail with a thick head, originally used in footwear to provide durability and traction, resembling the stoutness of a hob.
Think of a 'stout man' ('hob') and a 'metal fastener' ('nail') — a hobnail is a sturdy nail that gives strength to shoes.
