Orthotics and other types of shoe inserts are primarily designed to reduce injury and improve comfort. The interaction between the plantar surface of the foot and the load-bearing surface contributes to foot and surface deformations and hence to perceived comfort, discomfort or pain. The plantar shapes of 16 participants' feet were captured when standing on three support surfaces that had different cushioning properties in the mid-foot region. Foot shape deformations were quantified using 3D laser scans. A questionnaire was used to evaluate the participant's perceptions of perceived shape and perceived feeling. The results showed that the structure in the mid-foot could change shape, independent of the rear-foot and forefoot regions. Participants were capable of identifying the shape changes with distinct preferences towards certain shapes. The cushioning properties of the mid-foot materials also have a direct influence on perceived feelings. This research has strong implications for the design and material selection of orthotics, insoles and footwear.
矫形器和其他类型的鞋垫主要用于减少损伤并提高舒适度。足底与承重表面之间的相互作用会导致足部和表面变形，进而影响到感知到的舒适度、不适感或疼痛。16名参与者在站立于中足区域具有不同缓冲特性的三个支撑表面上时，其足底形状被捕捉。使用3D激光扫描对足部形状变形进行量化。通过问卷来评估参与者对感知形状和感知感觉的看法。结果表明，中足结构可以改变形状，与后足和前足区域无关。参与者能够识别形状变化，并对某些形状有明显的偏好。中足材料的缓冲特性也对感知感觉有直接影响。这项研究对矫形器、鞋垫和鞋类的设计及材料选择具有重要意义。
