Recommended events: All track events [100m-1500m / Hurdles / Long Jump / Triple Jump / Pole Vault] Excerpt from the manufacturer's website: Equipped with support parts for the arch of the foot. ARCHWRAP, located near the midfoot of the insole, works in conjunction with the shoelaces to support the arch of the foot inside the shoe. The plate has moderate stiffness in areas where force is easily applied, such as the ball of the big toe, to prevent excessive twisting. The forefoot has a plate with increased flexibility, and the heel has AHARPLUS with excellent abrasion resistance. The upper is reinforced with synthetic leather to improve breathability, hold, and durability. The pins and attachments can be replaced to suit track conditions. ARCHWRAP is a functional component designed to reduce the excessive drop of the arch (arch of the foot) during ground contact and reduce the burden on the athlete's foot. When using, you may occasionally feel discomfort in your foot. In that case, you can reduce the effect of ARCHWRAP and alleviate the discomfort by threading the shoelaces through the holes next to the loops along with ARCHWRAP.
