The World War II combat boot design evolved from the service shoes used with leggings. The Model 1939 "Shoes, Service, Composition Sole" was an ankle high shoe/boot made of tanned leather in a dark red color, originally with leather soles, changed to rubber soles after 1940. The same shoe design was modified in early 1943 (called Type III) to reverse the leather (rough side out) and add reinforcing rivets. A simplified version of the Type III shoe was adopted later in 1943 as the "Shoes, Service, Reverse Upper", different from the earlier service shoes in that it was built a little lower with no toe cap and with nylon laces instead of cotton. The latter two types were the most common service shoes of the war.

In the field, all of the service shoes where worn with leggings that extended the shoe up the calf. The leggings had a strap that looped under the shoe in the space in front of the heel. The leggings were laced up with a series of hooks and grommets. At the start of WW II longer leggings were in use in khaki or light OD shades. By 1944 a shorter, dark OD #7 legging was issued. Most ground troops wore the service shoe-legging combination until late in the war. Service shoes continued in use for garrison wear even after the war.

A World War II soldier received an initial issue of two pairs of shoes which could be resoled twice, then were replaced with a new or rebuilt pair. The replacement rate varied depending on conditions where the shoes were worn, ranging from a year in the US to only five months in the Southwest Pacific.
