Automation of shoe metrology is crucial to providing fit information for shoes on a large scale. Here, we examine a segmentation technique to extract the inner shoe volume (ISV) from Computed Tomography (CT) data-the proposed approach leverages artificial neural networks to extract shoe parts for automated metrology precisely. The neural network architecture is customized to facilitate the extraction of ISV by integrating spatial attention mechanisms. Furthermore, a neural network segmentation algorithm removes filler materials virtually. This process yields enhancements of 1.3% in F1-score through material removal and an additional 1.4% through the incorporation of spatial attention. Notably, spatial attention mechanisms yield improved outcomes at the aperture of the shoe. The elimination of filler materials reduces false positive segmentations. The segmentation outcomes are utilized to generate surface meshes. These are compared to surface meshes derived from annotated data. We measure an average Hausdorff distance between annotated and labelled data of 2.1 mm. The discrepancy is primarily attributed to deformations and artifacts. On both sets, we measure the effective shoe length. Precision and accuracy metrics for the extracted measurement from ANN-segmented data attain 0.8 mm and 1.8 mm, respectively. For meshes obtained from label data, the precision is 0.2 mm, and the accuracy is 2.5 mm. Our findings underscore the accuracy of the extracted shoe interior volumes, rendering them suitable for metrological applications. Limitations include unsolved issues with separation reliability and deformation.

“…The anthropometric grouping of articles were distributed into articles of footwear design (n = 36) which related anthropometric data to ergonomic design of children's footwear taking into consideration the age and perceived rate of foot growth [18,[101][102][103][104][105][106], gender [106], geographic region [107], body type [108], and developmental pathology [47]. The other articles (n = 2) considered the use of anthropometrics to formulate footwear assessment scores to quantify footwear fit in children [55,109].…”

Background Reports suggest that children with mobility impairment represent a significant proportion of the population living with a disability. Footwear is considered to be the key extrinsic factor affecting children’s gait and footwear modifications have been historically postulated to assist with locomotory difficulty. Although therapeutic footwear has been considered within the literature, there is a lack of consistency on terminology and paucity on the overall understanding. A scoping review was performed to chart the key concepts in children’s footwear and to establish the range of studies that considered therapeutic footwear. Methods A systematic search of MEDLINE, CINAHL, PubMed, SPORTdiscus, and Scopus electronic databases was performed using MeSH headings and free text terms in relation to children’s footwear. All studies that used footwear as an intervention in children aged 9 months to 18 years with the outcome measures including design, fit, and the effects on development and health were included. Studies were charted by textual narrative synthesis into research groupings dependent on the topics discussed and the methods used in the studies. Results The search yielded a total of 5006 articles with 287 of these articles meeting the inclusion criteria. Two overarching areas of research were identified; articles that discussed footwear design and those that discussed the effects of footwear. Eight further general groupings were charted and apportioned between the overarching areas and therapeutic footwear was charted into three subgroupings (corrective, accommodative and functional). Conclusion Children’s footwear has become an increasing area of research in the past decade with a shift towards more empirical research, with most of the included articles examining biomechanical and anthropometric aspects. However, children’s therapeutic footwear has not shared the same recent impetus with no focused review and limited research exploring its effects. Empirical research in this area is limited and there is ambiguity in the terminology used to describe therapeutic footwear. Based on the findings of this review the authors suggest the term children’s therapeutic footwear be used as the standard definition for footwear that is designed specifically with the purpose to support or alleviate mobility impairment in childhood; with subgroupings of corrective, accommodative and functional dependent on the intended therapeutic role.
