A dual-layer midsole pairs sustainable CircleCELL foam—engineered for energy return comparable to premium PEBA foams while doubling durability—with a rubberized EVA base for responsive cushioning and stability. The optimized 42 mm stack height is designed to support both speed work and distance training, preparing you for race day with confidence. The innovative TUNEDFIT dual lacing system lets you customize fit independently across the forefoot and midfoot, adapting as your feet naturally swell during longer runs and transforming potential discomfort into sustained energy and performance.
