The Montrail Stratos XCR shoe seamlessly blends the protection of a hiking boot with the ultralight technology and comfort of a trail runner. If you liked Montrails Excelerace, you'll love the Stratos. The Stratos is easier to put on, offers more ankle support and is more durable. What more could you ask for? Well for starters, the Gore-Tex EXO upper material gives you the ultimate in waterproof protection. One of the reasons for the incredible fit of the Stratos is the inner bootie construction that creates a smooth contact surface in front of the ankle. No more pinching, bunching or painful break-in periods. The full-length IntegraRide II protection plate provides lightweight, secure footing, which in turn gives you peace of mind and room to run. The Stratos is a super technical, incredibly comfortable, impressively functional waterproof hiker.
