The calf-high pull-on jackboot had been the traditional footwear of the German soldier for generations. The Wehrmacht boot was little different from that of World War I: made of brown pebbled leather (blackened with polish), with hobnailed leather soles and heel-irons. Trousers were worn tucked inside. Originally 35–39 cm tall, the boots were shortened to 32–35 cm in 1939 in order to save leather. By 1940 leather was becoming more scarce and issue was restricted to combat branches, and in 1941 jackboots were no longer issued to new recruits. By late 1943 production of jackboots had ceased altogether. However, as late as fall 1944 depots were encouraged to issue Marschstiefel to infantry and artillery, to the extent they were available.
