Regarded by experts and running enthusiasts as Montrail's most supportive and stable training shoe the Hardrock is also incredibly comfortable and ideal for those who dare to run further than a 70-mile week. Inside the Hardrock is a full-length TerraFlex™ AR protection plate identical to the plate found in the award-winning Montrail Kinabalu but unlike the Kinabalu the Hardrock has gel in the forefoot to help cushion your feet on long runs. Lightweight airmesh along the tops and sides of the upper help you air it out when the competition heats up.
