The Gel-Cumulus 22 running shoe is the recommended choice for neutral runners who want a soft and flexible daily trainer with a great fit. This update features a one-piece superior mesh combined with a seamless 3D printing structure that balances support and comfort around the foot, giving you an excellent fit right away. Flytefoam midsole is softer than the previous version for comfortable riding. Under the heel where the foot hits for the first time the ground has been redesigned to better insulate the impact. This new heel design has deeper grooves on the forefoot and a softer midsole foam to give you a soft drive. A durable AHAR rubber sole has been placed in key contact areas to help the Gel-Cumulus 22 shoe withstand a ton of miles.
