Tanker boots are military boots closely associated with soldiers who serve on tanks and tracked vehicles in general. It is said the idea was borrowed from the French crewmen encountered during World War I when then-Captain George S. Patton, Jr. established the United States Tank Corps. Whereas regular combat boots are laced through metal eyelets in the leather upper, the tanker boots are fastened with leather straps which wrap around the upper and buckle near the top. This benefits the wearer in several ways:
Tanker boots have a significant disadvantage over traditional lace up combat boots in that they provide comparatively little ankle support; however for troops that fight sitting in an armoured vehicle, this is relatively unimportant. An unauthorized variant of the tanker boot is the cavalry boot, or 'cav boot', which is higher above the ankle (in imitation of riding boots worn by the old horse cavalry) and might be worn by soldiers assigned to armored cavalry squadrons and scout units. The cav boots are more commonly seen being worn by officers in armored cavalry units.
