ASICS Performance Fujispeed 4

The ASICS Fujispeed 4 running shoe in green, size 45, is designed for road running and focuses on lightness and responsive cushioning. This model features ASICS FlyteFoam midsole technology, which provides consistent cushioning and energy return throughout the run, combined with a Guidance Line system that enhances gait efficiency from heel strike to toe-off. The engineered mesh upper offers breathable support and a secure fit, while the AHAR rubber outsole in high-wear areas increases durability. The shoe has a drop of approximately 8 mm, weighs about 250 g per shoe in size 45, and has dimensions of approximately 30 cm in length, 10 cm in width, and 12 cm in height. It includes a removable insole for customization and is suitable for neutral runners seeking a balance between speed and comfort on paved surfaces. The green colorway provides good visibility during daylight runs. This shoe is the successor to the Fujispeed 3, with updates to the upper construction for improved fit. It is recommended for training sessions, tempo runs, and races up to half marathon distance on roads. The materials are designed for regular use, with hidden seams in high-stress areas and a durable outsole pattern that maintains traction on both dry and wet surfaces. Care instructions include cleaning with a damp cloth and air drying away from direct heat sources to preserve the materials and structure.
