Under high-intensity and high load military activities, their feet bear much more pressure than ordinary people. The research found that the long-time load will change foot structures and cause foot injuries which play a negative role in training effects. Therefore, as for soldiers, foot health and protection should be put emphasis on. However, the domestic design of military footwear has not taken the influence of load exerting on the foot into consideration, thus, it’s necessary to discuss the effects of load playing on the foot. The research recruited 30 male military personnel as research subjects and observed the change of foot type of right foot under slight weight-bearing load, half weight-bearing load, half weight-bearing load of front and half weight-bearing load of back with the application of 3D scanning measurement technique and then calculated 25 foot dimensions. We can learn from the research that the measurement size of foot under light load was significantly different from those under 3 other loads and the length and width would increase with weight growth; the height reduced relatively and the girth kept the same. Later, we found from one-way analysis of variance that the load had significant effects on “Maximum Heel Width, Width at Distal Instep, Width at Short Heel Girth, Arch Height, Short-Heel Height, Instep Height, Max. Toe Box Height, Height of the Most Medial Point of Medial Malleolus, Height of Sphyrion”. Among them, the foot arch height changed the most and the research analyzed the influence of weight-bearing position playing on the foot with Post-hoc Test, from the research findings, we can conclude that the loads on font and back foot have no significant difference on foot size. This research aims at providing academic references for the designs and improvements of footwear, shank fillers and other relevant products based on the analysis results of size changes of foot.
