If you loved the Olympus 2.5 you are going to love the complete makeover of the 3.0. It has been completely updated for more traction, stability and support on the trail. The new mesh is more durable and breathable with a new mountain pattern and the 4-point Gaiter. Thanks to the addition of InnerFlex and shaving 3mm of foam, the midsole is now more flexible and responsive. The heel is widened for a more stable platform, and the outsole groove has been widened for optimized traction in sloppy conditions.
