Tests were made of the value to foot health of support in the arch and heel of the feet of marching troops. The control shoes, army service shoe, Type III, and combat boots were compared with experimental shoes with a low heel, and with those in which steel shank support in the longitudinal arch had been removed. During the first few days of the experimental period, when the shoes were new, the highest incidence rates of lesions were reached for both control and experimental groups. There was no essential difference between the effect of the control and experimental shoes on the foot health of marching troops as evidenced by the frequency, type, duration, distribution, time of onset, and severity march time lost due to lesions of the clinical lesions present. In the shankless shoe experiment, the superficial lesions constituted 79 of all lesions, the deep lesions 21 in the low-heel experiment, superficial lesions made up 57 of all lesions. The most common lesions were blisters, erythema, callus, and deep pain. Most lesions were located in the toe, metatarsal, and heel regions.
