Climbing activities affect cliff site species. With cliff sites harbouring unique species communities, the rise in popularity of outdoor climbing activities is a major threat. In this study, we assessed a previously unclimbed boulder before, during and after 500 climbing ascents. We observed an overall reduction in lichen cover by 4.2–9.5%, located around the footholds and combined foot- and handhold but not the handhold. We found the reduction in lichen cover to be strongest at the very start of the climbing treatment and to lessen over time. Therefore, management should focus on directing climbing activities to selected sites, while protecting sites with high conservation value where climbing is prohibited entirely.

“…Their analysis revealed that prolonged use and running over certain distances lead to reduced heel absorption due to foam wear in this area. Hale et al [78] employed a 3D finite element (FE) model to investigate the friction coefficient during walking, focusing on the influence of sole groove shapes on slip resistance in rubber footwear. Their study demonstrated a significant effect of sole surface and ground interaction on the friction coefficient, suggesting that different groove shapes and materials could further improve slip resistance.…”

Computer technology influences the capability to enhance the functionality of manufacturing and product design technologies. Innovations in computational design and digital manufacturing empower designers and manufacturers to create novel representations and algorithms for designing, analyzing, and planning the production of highly complicated products achievable through state-of-the-art technology. Various principles, including computational physics, geometric reasoning, and automated spatial planning, enable engineers to generate entirely new categories of products in the footwear industry. This study aims to review the methods and tools that have been published in the literature for the last twenty years, and provide a better understanding of the parameters, tools, and controls that contribute to the design and manufacturing processes of shoes. The main focus is on highlighting the product design-related trends within the footwear industry. A structured framework becomes apparent in the literature through the grouping and presentation of information. This framework facilitates drawing conclusions about the trends and existing needs derived from in-depth research in the field of footwear. Additionally, it reveals the upcoming methods and tools that will contribute to the enhancement and development of this emerging and promising industry sector. In conclusion, the categorization limitation within the footwear industry could serve as the foundation for exploring key areas to be analyzed further in other industries, for instance, in furniture, clothing, and packaging.

These engineering features and tools might affect the ACOF in various ways, and it is therefore of high importance to test how a specific shoe performs under the various conditions of the test standard, and whether a new shoe design can achieve the EN ISO 20347 certification.…”

Slipping is a major cause of occupational accidents and numerous footwear factors and features, as well as the testing conditions, affects a shoe's ability to resist slipping. The aim of this study was to compare slip resistance certification data from five certified shoes with measurements performed on a mechanical test setup in accordance with the ISO 20347:2012 standard, as well as determining their performance in a biofidelic setup that resembles the biomechanics of slipping. Certification data attributed Shoe #3 with the highest slip resistance, and our mechanical assessment of the same footwear models showed that Shoe #2 had the higher slip resistance and was superior under more biofidelic testing parameters. Based on our mechanical evaluations, specific engineering considerations such as an increase in both the heel beveling and the midsole thickness can advantageously enhance slip resistance. Further investigation in a clinical setting will provide insights on how these engineered footwear adjustments could enhance friction and ultimately enhance occupational safety.
