目前的初步研究检验了增加鞋类横向宽度（支撑基部宽度）是否可以降低在光滑表面上转弯时因侧滑引起的跌倒风险。设计和制造了宽支撑基 (BOS) 鞋，通过在普通 BOS 鞋的侧面使用 70 毫米宽的平面连杆固定 BOS 延伸部分来实现横向加宽。对 16 名年轻健康男性进行了步态试验。受试者被要求在铺有甘油溶液的不锈钢地板上直线行走并向右转 60°。与普通 BOS 鞋相比，宽 BOS 鞋将侧滑导致跌倒的试验频率减少了 67%，支撑脚的滑移距离和滑移速度分别减少了 40% 和 35%。结果证明，增加 BOS 横向宽度可以有效降低侧滑引起的跌倒风险。
The present preliminary study examined whether an increase in the lateral width of footwear (base-of-support width) can reduce the risk of falling caused by induced lateral slip while turning on slippery surfaces. Wide base-of-support (BOS) footwear was designed and manufactured, with lateral widening achieved by fixing a BOS extension, using a planar linkage of 70-mm width on the lateral side of normal BOS footwear. Gait trials were conducted on 16 young healthy male adults. Subjects were instructed to walk in a straight line and to turn 60° to the right on a stainless steel floor covered with glycerol solution. As compared with the normal BOS footwear, the wide BOS footwear reduced the frequency of trials in which fall occurred due to lateral slip by up to 67% and the slip distance and slip velocity of the supporting foot were reduced by up to 40% and 35%, respectively. The results demonstrated the efficacy of increased lateral BOS width in reducing the risk of fall caused by induced lateral slip.
