A pair of shit shoes, trainers, sneakers, pumps, plimsoles, boots or sandals. Pritty much any bad footwear that either look ridiculous or have a shit brand name like a pair of 'Mercury Bravados' or 'Denver Destroyers'. Normally worn by a poor middle aged man who tries to look cool but fails epically.
Look at that guy over there, he's wearing a pair of clonkers.
