Altra debuted with the Instinct (and the women’s Intuition) and receives an attentive update to its successful design. The upper is completely new, with an engineered mesh that adjusts well to the foot. The lining is smooth, offering support while snugging up comfortably.
The footbed has a cushy feel, thanks to the polyurethane insole and EVA Strobel board—not entirely unique, but effective for comfort. The midsole is full-length EVA with a top layer of Altra’s A-Bound foam, and its zero-drop geometry lowers the foot’s position to a neutral plane from heel to toe. The well-segmented outersole offers a good degree of flexibility. The tough full-rubber compound—FootPod in Altra’s parlance—offers a reliable grip, and its full- contact design adds stability. This update retains the heritage it began with and advances the performance it has always delivered.
Testers: “Consistent comfort, fit, and ride. Room for my toes and feels good on the foot. Cushy, and just enough of it.”
