The F-Scan system was used to measure peak plantar pressures in 11 diabetics each with a unilateral great toe amputation and an intact contralateral extremity (nonamputated), to evaluate the effectiveness of five footwear-insole strategies: 1) extra-depth shoes without an insole, 2) extra-depth shoes with a Plastizote insole, 3) extra-depth shoes with a Plastizote insole and a metatarsal pad, 4) extra-depth shoes with a Plastizote insole and a medial longitudinal arch pad, and 5) extra-depth shoes with a Plastizote insole and a combination of metatarsal pad and arch pad. When we compared extra-depth shoes with and without insoles, peak pressures were significantly reduced with insoles under the first metatarsal, the lesser metatarsals, and the heel (p < 0.001) in feet with and without an amputation, as well as under the great toe on the contralateral foot (nonamputated, p < 0.001), but not under the lesser toes (giant toe, p = 0.088; nonamputated, p = 0.763). There was no significant difference between the different insole modifications.
F-Scan系统用于测量11名糖尿病患者的足底峰值压力，这些患者均为单侧大脚趾截肢，对侧肢体完整（未截肢），以评估五种鞋类鞋垫策略的有效性：1）无鞋垫的超深鞋；2）带有Plastizote鞋垫的超深鞋；3）带有Plastizote鞋垫和跖骨垫的超深鞋；4）带有Plastizote鞋垫和内侧纵弓垫的超深鞋；5）带有Plastizote鞋垫以及跖骨垫和弓垫组合的超深鞋。当我们比较有无鞋垫的超深鞋时，无论有无截肢，第一跖骨、小跖骨和足跟下方使用鞋垫时峰值压力均显著降低（p < 0.001），对侧脚（未截肢）的大脚趾下方也是如此（p < 0.001），但小脚趾下方未降低（大脚趾，p = 0.088；未截肢，p = 0.763）。不同鞋垫改良之间无显著差异。
