Abstract: Objective The purpose of this study is to evaluate the comfort and safety of elderly male subjects wearing experimental modified shoes for fast walking through biomechanics testing methods, so as to provide data reference for the next shoe redesign. Methods Perform a series of exercise biomechanics tests for 16 male subjects aged 55 to 65 years old wearing three different senior sneakers. Applying 100mm VAS score and plantar pressure parameters to evaluate the senior sneakers in terms of subjective comfort and biomechanics comfort comprehensively. Applying vertical ground reaction force, plantar center of pressure displacement and available friction coefficient to evaluate the comfort of senior sneakers in terms of attenuation characteristics, gait stability and sneaker slip resistance comprehensively. Results B shoes was significantly lower than A shoes in the average pressure and peak pressure in the 2nd – 5th toe bone area. In the 2-4 metatarsal region, shoes B were significant lower than shoes C in peak pressure; in the fifth metatarsal region, the average pressure and peak pressure of shoes C were significantly lower than those of shoes A and B; in the medial area of foot arch, the average force/pressure of C shoes was significantly higher than those of shoes A and B ; on the outside of the arch area, the average pressure of shoes B was significantly lower than that of shoes C, and the peak pressure was significantly lower than that of shoes A. ABC three pairs of shoes in vertical ground reaction force first, force values are significant differences; C shoes was significant higher than B shoes in the second vertical ground reaction force peak. COPX-LR of C shoes was significantly higher than A and B shoes, COPXD was significantly lower than B shoes. The results of friction coefficient show that the peak value of the palm stretching friction coefficient of B shoes was significantly higher than that of A and C shoes, and the peak time of C shoes and landing stage was significantly slower than that of B shoes. Conclusions B shoes have good comfort and safety performance, and achieve the expected results. However, further improvement is needed to reduce plantar pressure in the fifth toe bone area. When designing shoes, if only thickness design is adopted to achieve the damping buffer effect, it may have a negative impact on the gait stability of the elderly.
