Description
Lightweight, moderate-drop stability trainer with Altra's signature wide toe box. Designed for mild pronators seeking a natural fit and soft cushioning. Strongly positioned as a versatile, comfort-focused daily trainer in Altra's lineup.
Plush, flexible ride with mild, unobtrusive stability and a roomy, accommodating fit. Soft midsole balances ground feel and protection, though lacks snap for faster paces. Outsole durability and tongue security are recurring concerns limiting all-around performance.
Ideal for daily training, walking, and recovery runs for runners needing mild support. Best suited to those with wide feet or transitioning from zero-drop shoes. Not recommended for racing or tempo work, but excels as a comfort-first option for easy miles.
