The Mystic makes the miles disappear. Plush cushioning underfoot, breathable mesh, and lightweight but supportive synthetics on the upper, are everything you need to make your runs more enjoyable. The Heel GRID System midsole offers stable heel cushioning, while the IMEVA midsole provides a cushioned underfoot ride. Extended HRC Impact Zone provides better transition through midfoot. The Flex grooves outsole creates a more flexible ride, and the XT-600 carbon rubber offers exceptional abrasion and traction properties.
