Its feature is its light weight, approximately 129 grams (27.0cm/one shoe). Designed for elite runners who prioritize a bouncy and light running feel, it is especially effective for forefoot running (running that lands from the front of the foot (toe)). The midsole and insole use "FF LEAP," a new material developed by ASICS, which is the lightest and most responsive cushioning foam material among their proprietary materials. Compared to the previous model ※ using "FF TURBO PLUS," it is approximately 15.0% lighter, with approximately 13.7% better rebound and approximately 30.0% better cushioning. It deforms and compresses upon landing and quickly returns to its original shape, providing a bouncy sensation that allows you to extend your stride. In addition, a lightweight carbon plate is embedded inside the midsole to stabilize foot movement and effectively propel the body forward. The upper uses "MATRYX®," a lightweight and breathable material. It offers excellent fit, suppresses wobbling during high-speed running, and supports stable footwork. The outsole uses "ASICSGRIP," which provides excellent grip on various road conditions. Made in Vietnam Material Insole material: Synthetic resin (FF LEAP) / Fixed The insole used in this product may initially float, but the adhesion will stabilize with repeated use and will eventually become fixed. Please be aware of this.
