Medio-lateral and lateral edge friction in indoor sports shoes

It has previously been speculated that the occurrence and severity of lateral ankle sprain injuries is linked to excessive shoe–surface friction. Especially, parts shoe outsole are suggested play an important role in such scenarios but have never quantified a systematic manner. Therefore, purpose this study was investigate variation friction indoor sport shoes with foot orientation compare it traditional industry forefoot test standard. We modified ISO:13287:2019 for footwear slip resistance positioned on its edge while replicating medio-lateral movements similar reported incidents. All tests were conducted vinyl/sport surface. The results from setups compared those following anterior-posterior orientated ISO Medio-lateral average 17% lower 24% than (p < .001). However, linear regression showed could only explain 36% 35% This suggests motion-specific necessary determine properties meaningfully. These findings implications future research product testing field friction, safety injury prevention.
