Non-leather Chelsea boots.
Chelsea Boots, also known as dealer boots and, as a riding boot jodhpur boots or paddock boots, are tight-fitting, ankle-high boots that originated in the Victorian era, and were first used for horse riding. The most notable feature of the Chelsea boot is its elastic siding, running from just above the welt to the top of the shoe. The design began as a type of riding boot known as paddock boots or jodhpur boots. Chelsea boots were considered an element of the 1960s mod scene, and they have recently become in fashion again amongst men as well as women. Similar boots are the heavier Australian work boots which are popular in Australia.
Charles Goodyear's development of vulcanised rubber enabled Sparkes-Hall, bootmaker to Queen Victoria, to invent the elastic gusset boot in 1837. The advantage of elasticised boots meant they could be easily removed and put on again, which appealed to busier and more demanding lifestyle of Victorian women. By the late 1840s, the fashion began to catch on. This became a prominent style in the West until the onset of World War I.
The boots were featured in the first three Star Wars films, worn by the stormtroopers of the Empire. The stormtrooper boots were standard black Chelsea boots which were stained white.
Black steel-toe Chelsea/dealer boots are issued to US Navy flight deck personnel who work with liquid oxygen (LOx), hence they are known as LOx boots. These were preferred to traditional lace-up boots since the laces on the latter would freeze upon contact with liquid oxygen making them very difficult to remove and possibly cause harm to the wearer.
