Wedge boots, wedgies or lifties are a type of high heel where the shoes and boots have a sole in the form of a wedge so that one piece of material, normally rubber, serves as both the sole and the heel. The design dates back to ancient Greece. Wedge boots are more common for women and often have a sole that is much thicker at the back than the front, making it a high-heel shoe or boot. Wedges for women were popularized by Salvatore Ferragamo who introduced the design to the Italian market in the late 1930s.
Men's wedge boots,usually called "wedgies", usually have a low heel. These wedged boots became popular during the 1970s. They are making a comeback in 2010s.
Some forms of wedge boots, called platform boots, have thick soles throughout.
