The arches of foot play important roles in the foot pressure distributiondynamic stability during walkingrunning. The transverse arch has been shown to be closely related to foot stiffness. There are few studies on wearing insoles with transverse arch supported elements,the related biomechanical effects are still possible to be further explored.

The Nature reported that, through the inter-metatarsal tissues, the contribution of the transverse tarsal arch for the longitudinal stiffness of the foot is greater than 40 (Venkadesan et al., 2020). In this study, a gyroscopea Pedar-X insole foot pressure measurement system were used simultaneously to compare the difference between the combining longitudinaltransverse archlongitudinal arch support insole involved during running test. Combining longitudinaltransverse arch support insole, the angular velocity of the metatarsal bone tends to decrease during running, which means that the foot has a smaller ankle internal rotation. Compared with the longitudinal arch support insole, the peak pressuremaximum force of th

The results of this study indicated that the combining longitudinaltransverse arch support insole can reduce the internal rotation angular velocity of the metatarsal bones of the foot effectively when running,it can also help runners reduce the plantar pressure at the first metatarsalthe heel effectively. The results of current study have applied to multiple local industries in Taiwan, including the transverse arch support sock for Titan, the transverse supporting insole for Long Term Concept,the inserted midsole for Victor, which is the event sports footwear for Chinese Taipei team of Tokyo Olympic. In the industry, it is necessary to consider the shapearch of users foot to adjust the heightposition of compon
