Hessian (boot) in the context of "Wellington boot"

A Wellington boot, gumboot, rubber boot, rain boot, rainboot, or welly for short, is a type of waterproof boot made of rubber.

Originally a type of leather riding boot adapted from Hessian boots, a style of military foot wear, Wellington boots were worn and popularised by Arthur Wellesley, 1st Duke of Wellington. They became a staple of practical foot wear for the British aristocracy and middle class in the early 19th century. The term was subsequently applied to waterproof rubber boots ubiquitously worn today in a range of agricultural and outdoors pursuits.
