“骑行”是一个偶尔用来描述跑步时鞋子感觉的术语，但它从未被正式定义，也没有任何关于如何客观测量“骑行”的建议。在这项研究中，我们提出了一个定义为“骑”，涉及到的平稳过渡的脚通过步态的立场阶段，并建议，峰值速度在前后方向来自压力中心将是一个适当的措施来量化“骑”。然后，我们使用实验证据来倡导这种评估的适当性。13名参与者穿着两双具有不同中底顺应性的鞋子跑了160米，并主观评估了每双鞋子的“骑行”和舒适度。压力中心是从压力传感鞋垫测量的，前后方向的峰值速度是从脚跟到前脚的过渡。结果发现，个体能够感知鞋的“骑行”，并且具有较低峰值速度的鞋与显著较高的“骑行”和舒适度评分相一致（p < 0.001）。然而，并不总是中底较软的鞋具有更平稳的“骑行”，因为13名参与者中有5名在刚性中底中具有更平稳的“骑行”。需要进一步研究，以了解为什么某些人有一个更顺利的'乘坐'在一个顺应性比一个僵硬的中底。这个概念在真实的世界中可能是有用的，并且可能在鞋店内实现，以帮助指导鞋子的选择。
'Ride' is a term that has been used occasionally to describe the feel of a shoe while running, yet it has never formally been defined nor have there been any suggestions of how to objectively measure 'ride'. In this study, we proposed a definition for 'ride', relating to the smoothness of the transition of the foot through the stance phase of gait, and suggested that the peak velocity in the anterior-posterior direction derived from the centre of pressure would be an appropriate measure to quantify 'ride'. Then, we used experimental evidence to advocate the appropriateness of this assessment. Thirteen participants ran over 160 metres in two pairs of shoes with different midsole compliance, and subjectively evaluated the 'ride' and comfort of each shoe. Centre of pressure was measured from pressure-sensing insoles and the peak velocity in the anterior-posterior direction was taken from the transition from heel to forefoot. It was found that individuals were able to perceive the 'ride' of a shoe and the shoe with the lower peak velocity coincided with a significantly higher rating of 'ride' and comfort (p < 0.001). However, it was not always the shoe with the softer midsole that had a smoother 'ride', as 5 out of 13 participants had a smoother 'ride' in the stiff midsole. Further research is required to understand why certain individuals have a smoother 'ride' in a compliant versus a stiff midsole. This concept could prove useful in the real world and could possibly be implemented within a shoe store to help guide the selection of a shoe.
