Engineer boots, also known as engineer's boots or engineering boots, are an American type of traditional leather work-boots. Their lace-less, rugged construction made them popular among motorcycle riders.
Originally developed in the 1930s for firemen working on steam locomotives, the boots gained substantial popularity in the post–World War II era during a growing motorcycling culture. They became popular symbols of teenage rebellion in the 1950s and a common component of greaser wear. They were later adopted by skinheads and punks in the 1970s. By the 2010s, engineer boots were being popularly worn for fashion purposes, especially by non-traditional customers such as women, young urban professionals, and hipsters.
