The ASICS GEL-Cumulus 21 running shoes for women have been fully updated. The Flytefoam midsole makes them lighter and more reactive than ever. The total ground contact sole promotes a more dynamic step rhythm. And of course, they include Gel at the front and back for excellent cushioning. Features: - Drop: 10 mm - Weight: 295 g - OrthoLite Template Technologies: - Impact Guidance System (I.G.S.) A technology designed by Asics to provide a smooth and balanced transition from the moment your foot hits the ground to the moment it leaves. - OrthoLite Anatomical sockliner that brings many benefits for the foot, those being high breathability, optimum moisture management, a lightweight feel and an antimicrobial treatment. - FluidRide The newest midsole technology from Asics. The FluidRide technology improves cushioning and bounce of the foot whilst keeping the lightweight feel of the shoe. - Guidance Trusstic The Trusstic Guidance system includes a Guidance Line construction to improve step efficiency at the same time as providing a stable structure for the midfoot. - Guidance Line The Guidance Line is a flexible vertical groove that runs the length of the sole and creates a more efficient step. - Visible Rearfoot and Forefoot GEL Cushioning System Reduces shock from the impact and impulsion stages of the foot and promotes movement on multiple planes as the foot transitions in the stride cycle. - SpEVA Midsole Material A midsole material whose composition, quickly returning to its original shape, means you can experience the best cushioning with every step as well as it being long-lasting. - 3M Reflective Material made by the company 3M that keeps you visible in the dark. - AHAR+ This rubber is highly abrasion-resistant as it is a firm rubber fixed to the heal area where the first and hardest impact of a step is felt, reducing the wear of the sole. - Removable Sockliner Individual eyelets that allow distribution of the lace tension and improve fit and comfort on the top of the shoe.
