Womens Gel-Cumulus 21

The ASICS Gel-Cumulus 21 features a more accommodating forefoot fit, added underfoot comfort and a softer landing. The Gel-Cumulus 21 has been upgraded from a Flytefoam midsole to Flytefoam Lyte to give the shoe a slightly softer and more comfortable ride. You will enjoy the new multi-directional mesh upper that reduces weight and enhances breathability. What’s new: More height in the toe box and across the ball of your foot. Better and more comfortable cushioning underfoot. New grooves in the sole under the heel for a softer landing. More foam in the heel collar for added comfort. Midsole Technology: Gel Cushioning System uses a silicone-based gel for responsive shock absorption on impact. Flytefoam Lyte provides lightweight and durable cushioning that is also environmentally friendly. Flytefoam Propel is a softer and bouncier foam added to increase responsiveness while maintaining comfort. Guidance Line is a flex groove that runs vertically from the heel to the forefoot for improved gait efficiency. Impact Guidance System (IGS) design creates a smooth and balanced heel-to-toe transition. Gender-Specific Cushioning uses an injected top layer of Solyte cushioning for additional comfort. Outsole Technology: Asics High Abrasion Rubber (AHAR) in the heel is made of carbon rubber for exceptional durability. DuraSponge Outsole in the forefoot is made from a blown AHAR compound for responsive cushioning and flexibility. Upper Technology: Multi-directional Mesh comprises the upper, providing lightweight breathability for a plush, irritant-free fit. Seamless Upper Construction allows for irritation-free sock less wear. Personal Heel Fit (PHF) uses a two-layer memory foam lining in the heel collar to provide an individualized fit. Contoured Sockliner matches the natural shape of your foot for a better fit.
