Arch-pad design and insole material jointly influence regional plantar loading and perceived comfort during walking in women’s occupational footwear
研究了鞋垫材料和足弓垫设计对女性职业鞋中足底压力和舒适度的影响，发现足弓垫能改变足底压力分布，材料影响较小且具区域特异性，为鞋垫原型设计提供参考。
This study examined immediate effects of insole material and arch-pad design on perceived comfort and in-shoe plantar pressure in women's occupational shoes. Sixteen healthy young women completed nine randomised within-subject conditions (polyurethane, open-cell foams or silicone × no pad, arch-pad 1 or arch-pad 2) during level walking in standardised 35-mm heel shoes. Plantar pressure (contact area, peak pressure and pressure-time integral) was measured with an in-shoe pressure system, and comfort was rated using a footwear comfort scale. Arch-pad conditions increased medial-midfoot contact area and reduced pressure-time integral in selected forefoot and heel regions, while increasing pressure-time integral at the medial midfoot and peak pressure at toes 2-5. Material effects were smaller and more region-specific, and material-by-arch interactions were observed for pressure-time integral at the lateral forefoot and medial heel. These acute findings may inform early-stage insole prototyping but require validation under longer-duration, task-representative occupational conditions.
