The Guide 8 is the ultimate training partner, providing stability with flexibility in a lightweight package. PowerGrid provides responsive cushioning from heel to toe. A fully decoupled SRC crashpad minimizes impact, and the redesigned medial support system creates a smooth transition to midfoot. A flared forefoot design adds support during toe-off allowing the runner to spring forward efficiently and powerfully. Added flex grooves ensure the shoe moves with the runner with comfort and responsiveness.
