By stimulating the "Yusen" (Kidney 1) point on the sole of the foot with this ball, fatigue can be reduced, foot pain and metatarsalgia can be relieved, and overall relaxation can be promoted. 【Relieves Foot Pain】Our metatarsal insoles are designed to relieve foot pain such as plantar fasciitis, heel spurs, Achilles tendinitis, metatarsalgia, bunions, and lower back pain. High arch insoles help reduce discomfort. 【Materials and Structure】The arch support part uses hard TPU material, effectively supporting the arch and withstanding a weight of approximately 100kg or more. The surface of the metatarsal support uses breathable velvet material, providing antibacterial and deodorizing effects. Furthermore, the EVA and Ortholite foam layers provide excellent shock absorption. 【Designed for Daily Use】The bunion-compatible insoles are designed based on human engineering to promote correct foot alignment. We recommend these medical flat foot insoles for teachers, service industry workers, office workers, and others who require long hours of standing or walking. 【Appropriate Size】To make the arch support insoles fit your feet better, select the closest size. Also, make sure there is enough space to insert the shoe insole. 【Advice】If you are using arch support insoles for the first time, start with 2-3 hours a day and gradually increase the usage time until your feet adapt to the metatarsal insoles.
