This shoe is for the user who wants to have extra cushioning, whether for longer runs, recovery runs, or when running with a backpack. To improve comfort and excellent running feel, it has a rocker midsole to reduce pressure on the forefoot and heel and promote forward momentum, providing a smooth stride. The midsole is made of compression molded EVA, allowing for a natural dual density where the forefoot has a higher density, providing greater response at toe-off. This provides great comfort on longer runs while also providing responsiveness and a great running feel. The RB9X™ sole provides traction on both dry and wet surfaces, making the Arcus the perfect running shoe in most weather conditions.
