Many researchers investigate how footwear design affects plantar pressure (PP) and ask participants to walk in unfamiliar footwear as part of their studies. However, there are no clear guidelines for the required period of time or number of steps a healthy participant requires to acclimatise to unfamiliar footwear. Nor are there clear guidelines for how many steps should be collected to produce data that is representative of gait in each particular shoe being tested. There were therefore two aims to this study: (1) to investigate the number of steps required to produce an average step that is representative of normal gait; (2) to investigate the number of steps required for a participant to acclimatise to a range of footwear types. PP data were collected in 20 healthy participants whilst they walked for 400 m in a range of footwear. The results showed that the number of steps required for both acclimatisation and to ensure data quality are dependent on shoe type and the foot region being investigated. It is recommended that 30 steps from one foot are collected during data collection and an acclimatisation period of at least 166 steps is given for each shoe condition. The former recommendation is not met by most studies in the literature.
许多研究人员研究鞋类设计如何影响足底压力 (PP)，并要求参与者在研究中穿着不熟悉的鞋子行走。然而，对于健康参与者需要适应不熟悉的鞋子所需的时间或步数，以及为了使在每种特定测试鞋中采集的数据具有代表性需要采集多少步，都没有明确的指导方针。因此，这项研究有两个目的：(1) 研究产生代表正常步态的平均步的所需步数；(2) 研究参与者适应一系列鞋类所需的步数。在 20 名健康参与者穿着一系列鞋子行走 400 米的过程中，收集了 PP 数据。结果表明，适应和确保数据质量所需的步数取决于鞋子类型和正在研究的足部区域。建议在数据采集期间从一只脚收集 30 步，并且对于每种鞋的条件，至少给予 166 步的适应期。前者的建议在文献中的大多数研究中都没有得到满足。
