“…There is also no published data on how safety footwear is supplied to workers and protocols for when it is replaced in the wine industry. Recent research into shoe tread (sole) wear and wear measurement has highlighted the need for understanding the mechanism for shoe tread wear and individualised shoe replacement recommendations to prevent injury caused by the decline in traction of worn shoes [47][48][49].…”

Background The Australian wine industry is a valuable part of the wider Australian economy worth approximately A$45 billion annually and employs 163,790 people either full time or part time. Australian agricultural industries are amongst the nation’s most dangerous workplaces with joint, ligament, muscle and tendon injuries being commonplace along with wounds, lacerations and musculoskeletal diseases. It is therefore important to try and minimise the risk of injuries to workers. The aims of this study were to (1) identify whether lower limb problems occur in the Australian wine industry and (2) identify the types of safety footwear worn. Methods Participants were recruited from the Australian wine industry. The study was a cross-sectional anonymous survey of 82 questions with n = 207 respondents. Questions related to job role performed, types of lower limb problems experienced, level of pain, restriction of activities, types of footwear worn, general health and physical health. Results The main working roles were winery (73.4%), vineyard (52.2%), laboratory (39.6%), cellar door (32.4%) and office (8.2%), with 63.3% of participants working in more than one role. Lower back pain was the most commonly reported problem at 56% followed by foot pain (36.7%), knee pain (24.6%), leg pain (21.3%), ankle pain (17.9%), hip pain (15.5%), toe pain (13%) and heel pain (11.1%). The most popular footwear used by participants were elastic sided safety boots, followed by high cut lace up safety boots with side zip. Overall, although the pain experienced was moderate, it did not impact the workers ability to perform their duties and the majority self-reported as being in very good general and physical health. Conclusion To date no data have been published on the types of lower limb problems or the types of safety footwear worn in the Australian wine industry. This study is the first to demonstrate that elastic sided safety boots were the most popular amongst respondents and that lower limb problems occur with workers. Therefore, further research into the safety footwear used in the Australian wine industry is needed to better support workers health while working in their varied roles and conditions.

“…Recent publications describe tools being developed for the advancement of insole pressure measurements for sports (Krüger & Edelmann-Nusser, 2009) and fall risk assessment (Subramaniam et al, 2022), as well as an outsole measurement tool for slip prevention (Whitson et al, 2018). Giles and Vallandingham (1991) discuss relationships between foot, footwear, and footprint measurements with regard to a persons' height but do not include footwear insole measurements or specific outsole measurement techniques.…”

SAR resources, including visual trackers, conduct missions for thousands of missing persons every year. These missing persons, who may be wearing footwear, usually own additional pairs. To aid with track interpretation and possibly expedite finding the person, trackers can glean useful information from the other samples. Relationships between footwear measurements are described for four parameters: insole length, outsole length, outsole width, and heel width. Insole lengths vary less than outsole lengths for individuals. The outsole length, outsole width, and heel width portray linear relationships to insole length with excellent, fair, and poor reliability: R2 = 0.95, 0.84, and 0.65, respectively. The results of these findings provide footwear dimension predictions and offer benefits for clue interpretation. KEYWORDS: Search and Rescue, Tracking, Footwear, Tracks, Dimensions

“…The foot dimensions used in the study were measured from scanned digital foot models using virtual tools (PolyWorks Software, InnovMetric Software, Quebec, QC, Canada). PolyWorks allows precise measurements along the sagittal (x) and transverse (y) axes and realigned foot axis (Schwarz-Müller et al, 2021;Whitson et al, 2018). The foot axis is defined as the line joining the pternion (Pte, the most posteriorly projecting point of the heel) and the centre point (CP) of the vertical cross-section passing through the MT and MF (Lee & Wang, 2015).…”

Differences in foot shape when wearing wedge-heeled shoes with elevated forefoot height and heel height

Wedge-heeled shoes, which are formed by elevating both the forefoot and heel, have been popular among young women. However, research on the foot shape in wedge-heeled shoes is lacking. This study aimed to access the effects of forefoot height (10, 20, and 30 mm) and heel height (30, 50, 70, and 90 mm) on foot shape and perceived comfort when wearing wedge-heeled shoes. Three-dimensional (3D) foot scanning was performed on 35 females and the 14 foot dimensions were measured. Increased forefoot height generated larger lengths (foot, ball and out ball), smaller girths (ball and instep) and heights (instep and navicular) (p < 0.05). Thus, when the forefoot height increased, the foot became longer, slimmer and flatter. Moreover, elevated heel height resulted in larger dimensions for girths (ball and instep), heights (instep and navicular), and smaller dimensions for lengths (foot, ball and out ball), widths (diagonal and horizontal) and toe 5 angles of the foot (p < 0.01). That means shorter, narrower and more convex foot shapes were observed when heel height increased. Subjective measurements implied that increased forefoot height significantly enhanced perceived comfort, whereas increased heel height diminished comfort. It was found that forefoot elevation could result in less deformation and discomfort which accompanied heel elevation, especially in the low heel-toe drop combinations (10 × 30 and 20 × 30 mm). The findings provide valuable references for enhancing shoe fitting and comfort for wedge-heeled shoes by providing dimensional data on the toe, ball, arch and instep regions.
