The determination of pressure patterns underneath the footsole inside skiboots, may reveal reasons for footpain and injury risk. In our study, a new developed 72 point measuring mat was used in 5 different skiboots. Data were collected in 10 subjects in different forward flexion positions. In addition a determination of the pressure distribution over the instep was done by means of single measuring points. The results proof, that a proper adapting along the dorsum of the foot does lower the forefoot load during flexion. A tightly closed and well adapted boot will lead to a significant reduction of the total load on the footsole. High shaft models show similar pressure patterns even at earlier forward flexion angles. A pressure related discrimination between rear entry and traditional boots, that was found along the tibia, was not the case underneath the footsole. The force transmission is mainly performed along the shaft of the boot. The effect of orthotics designed mainly to support steerability of the ski, is therefore doubtful. The results may help to improve our knowledge of the interaction between boot and skier and lead, together with future field research, to a reduction of equipment related injuries.
确定滑雪靴内鞋底下方的压力模式，可能会揭示足部疼痛和受伤风险的原因。在我们的研究中，一种新开发的72点测量垫被用于5种不同的滑雪靴。在10名受试者处于不同前屈位置时收集数据。此外，通过单个测量点对脚背的压力分布进行了测定。结果证明，沿着脚背进行适当的适配确实会降低前屈时前脚掌的负荷。紧密贴合且适配良好的靴子将显著降低鞋底的总负荷。高帮款式即使在前屈角度较小时也显示出类似的压力模式。在胫骨处发现的后入式靴子和传统靴子之间与压力相关的差异，在鞋底下方并未出现。力的传递主要沿着靴子的鞋帮进行。因此，主要设计用于支持滑雪操控性的矫形器的效果值得怀疑。这些结果可能有助于增进我们对靴子与滑雪者之间相互作用的了解，并与未来的实地研究一起，减少与装备相关的伤害。
