[From the manufacturer's press release below] The product being released this time is equipped with a carbon plate from the front to the rear of the midsole (the cushioning material between the upper and the sole). The plate has a V-shape and is angled downwards towards the toes, stabilizing the foot's movement from landing to toe-off and effectively propelling the body forward. It was named "S4" because it possesses four elements: "Speed," "Stability," "Safety," and "Sub4." The midsole has a two-layer structure, with the upper layer using the proprietary lightweight cushioning foam material "FF BLAST TURBO," which is also used in the higher-end "METASPEED" series. It deforms and compresses upon landing, and quickly returns to its original shape, providing a bouncy sensation and allowing for longer strides. The upper uses "MOTION WRAP UPPER," which is lightweight and highly breathable. It has excellent kick-back properties and improves the fit, especially in the midfoot. The sole uses "ASICSGRIP," which provides excellent grip on various road conditions.
