Worn on 2 runs! Tons of miles left The GEL-CUMULUS® 23 shoe's focus is to provide an even smoother and softer ride. Continuing to draw inspiration from cumulus clouds, we reimagined this neutral running shoe's upper and midsole formation by applying a more holistic design approach that adapts to the runner's anatomy in motion. Wrapping the foot with an even softer feel, the engineered mesh upper adds strategic support in targeted areas while leaving some of the fibers more open to improve breathability. The upper also works more closely with the midsole's movement, which creates a smoother stride from footstrike to toe-off. Additionally, the shoe's upper is made with recycled materials to reduce waste and carbon emissions. To improve cushioning and flexibility, we added a 3D SPACE CONSTRUCTION™ to the top layer of the midsole. By helping runners appropriately compress the foam during the landing phase of their stride, this shoe promotes a smoother ride and improves shock absorption. Lastly, a softer GEL® technology unit is positioned under the heel to improve cushioning while the FLYTEFOAM® midsole material helps create a smoother and more supportive ride.
