There is a causal relationship between diabetic foot ulceration, elevated plantar pressure, and severe sensory neuropathy. Cushioned footwear intended to relieve plantar pressure is well established for prevention and healing of plantar ulcers. The aim of the present study was to investigate whether pressure relief by means of a running shoe with optimized forefoot pressure damping is comparable to that of a custom-made soft insole placed into an in-depth shoe. The in-shoe pressures were compared to an in-depth shoe with the original cork insole and with a leather-soled Oxford shoe. The maximum reduction of plantar pressure in the running shoe was 47% under the 2nd and 3rd metatarsal heads, 29% at the first metatarsal head, and 32% at the great toe in comparison to the Oxford shoe. This was surpassed only by the custom-made insole, which reduced pressures at the metatarsal heads by 50%. The specially designed running shoe yielded the same pressure relief at the central metatarsal heads as the custom-made insole. Such shoes are likely to be very useful in preventing diabetic foot ulceration in high-risk patients as a comparatively affordable and immediately available device.
糖尿病足溃疡、足底压力升高与严重感觉神经病变之间存在因果关系。旨在减轻足底压力的缓冲鞋对于预防和治疗足底溃疡已得到充分认可。本研究的目的是调查通过具有优化前足压力缓冲功能的跑鞋减轻压力的效果是否与置于深度鞋内的定制软鞋垫相当。将鞋内压力与配有原始软木鞋垫的深度鞋以及皮鞋底牛津鞋进行比较。与牛津鞋相比，跑鞋在第2和第3跖骨头下方的足底压力最大降低了47%，在第1跖骨头处降低了29%，在大脚趾处降低了32%。只有定制鞋垫超过了这一效果，其在跖骨头处的压力降低了50%。特别设计的跑鞋在中央跖骨头处产生的压力减轻效果与定制鞋垫相同。作为一种相对经济实惠且可立即使用的装置，此类鞋子可能对预防高危患者的糖尿病足溃疡非常有用。
