Footwear may be found at crime scenes as physical evidence. Such footwear often has impression features of the wearer's foot on the insole of the shoe. Scientific research and literature have established that footprints are distinct. This study compares two-dimensional measurements on bare footprints to foot impressions on insoles to determine if significant differences or similarities exist. Dynamic footprints were collected from 51 donors using theIdenticator® Inkless Shoe Print Model LE 25P system. Seven foot length and width measurements were taken based on the Reel linear measurement method. Footprint measurements between bare footprints and foot impressions on the insoles were compared. Only two differences (p > 0.05) were observed between the various bare footprint and insole foot impression measurements on the right and left side for most of the measurements, CALC (p < 0.001) and A1 (p = 0.04). Bare footprint and insole A5 measurements on the left side were also significantly different (p = 0.015). The results of the study have implications in the forensic analysis of foot impression evidence on insoles in footwear in assisting with identifying the wearer of said footwear. Situations may arise in the forensic context when comparing the foot impression on the insole of footwear to a suspect's bare footprint or a footprint from post-mortem remains. This study contributes to the scant literature available on the topic and to understanding the similarities and differences observed in the various linear measurements that may be utilized in the comparison process of footprint impressions on shoe insoles to bare footprints.
鞋类可能会在犯罪现场作为物证被发现。此类鞋类通常在鞋底内有穿着者脚部的压痕特征。科学研究和文献表明脚印是独特的。本研究比较了赤脚脚印的二维测量结果与鞋底上的脚印压痕，以确定是否存在显著差异或相似性。使用Identicator®无墨鞋印模型LE 25P系统从51名捐赠者处收集了动态脚印。基于卷轴线性测量方法进行了七次脚长和脚宽测量。比较了赤脚脚印与鞋底脚印压痕之间的测量结果。在大多数测量中，左右两侧的各种赤脚脚印和鞋底脚印压痕测量之间仅观察到两个差异（p>0.05），CALC（p<0.001）和A1（p = 0.04）。左侧的赤脚脚印和鞋底A5测量也存在显著差异（p = 0.015）。该研究结果对鞋类鞋底脚印压痕证据的法医分析具有启示意义，有助于识别所述鞋类的穿着者。在法医背景下，可能会出现将鞋类鞋底的脚印压痕与嫌疑人的赤脚脚印或死后遗体的脚印进行比较的情况。本研究为该主题现有的少量文献做出了贡献，并有助于理解在鞋类鞋底脚印压痕与赤脚脚印的比较过程中可能使用的各种线性测量中观察到的异同。
