Recently at the F/W 2018 collection , Paris Men’s Fashion Week, Chinese imprint SANKUANZ, had plastic "shoes for shoes" modelled on the catwalk. The reintroduction of the patten was driven by fashionistas keen to wear A-list sneakers outside but equally concerned at keeping the blue-chip trainers in pristine condition.
Pattens has been around for centuries and were first worn nobility to protect the their expensive poulaines in the 11th century.
Platform like slip-over shoe protectors were used as outside shoes and were made from wood or metal to protect the encased and more delicate shoes from wet and muddy ground. Pattens were left outside. These were widely used between the 16th and 18th centuries.
