Abstract:

Historically, blisters have plagued the feet of infantry forces and reduced the combat effectiveness of military units. The purpose of this study was to test the ability of prototype sock system to reduce blister incidence in Marine recruits at Marine Corps Recruit Depot, Parris Island, SC, from May to August, 1992. Subjects were separated into three groups. The first group wore the standard issue sock consisting of a woolcotton-nylon-spandex combination group SS, N160. The second group wore the standard sock with a thin inner sock consisting of polyester group SL, N106. The third group wore the same thin inner sock and a thick, dense, prototype outer sock consisting of a wool- polypropylene combination group PL, N91. Recruits in the PL group suffered significantly fewer blisters compared to recruits in either the SS roup 40 vs 69, p0.001 or the SL group 40 vs 77, p0.001. The rate of lister occurrence was also less in the PL group 11 blisters100 recruitsweek compared to the SS group 28 blisters100 recruitsweek or the SL group 26 blisters100 recruitsweek. Blisters serious enough to require a sick call visit occurred with greater frequency in the ss group compared to both the PL group 24.4 vs 11.0, p-0.02 and the SL group 24.4 vs 9.4, p0.01 there was no difference between the SL and PL groups. Blister reduction was most apparent in the early weeks of recruit training. The prototype sock system reduced the overall incidence and severity of blisters in Marine recruit training....
