The Olympus 3 has been completely revamped for more support, stability, and traction on any terrain. The upper mesh is more breathable and durable and features printed mountain graphics and a 4-point GaiterTrap™. The midsole is more flexible and responsive now thanks to the addition of InnerFlex and shaving down the stack height by 2mm. The Vibram MegaGrip outsole has been widened in the heel area for increased stability, and the middle groove has also been widened for better traction in wet conditions. Stack Height: 33mm.
