Abstract : The test was conducted to determine the technical performance and safety characteristics of the spike resistant insole worn in the standard tropical boot when subjected to accelerated usage. It was found that a minimum force 265 pounds was required at point of contact to pierce the combined outsole of the tropical combat boot and the experimental insole. The insoles are unsatisfactory from a durability standpoint, being highly susceptible to deformation and cracking. The insoles produce foot discomfort due to excessive heating of the soles of the feet. The insoles are satisfactory from a safety standpoint. It was recommended that the experimental spike resistant insole be redesigned to prevent buckling of the steel plate, thus reducing cracking of the plate and diminishing the heat transmitted to the foot produced by flexing of the plate.
