You’re not the only one who took a double take at this new and improved Olympus 4, but be prepared for one of the most fun rides out on the trails. A new engineered mesh upper is breathable and durable, the two things that matter the most for long days (and nights) out on the trails, with an improved tongue for extra comfort and lockdown. The midsole is made with the stack height as in previous versions but with InnerFlex as well for enhanced flexibility and performance, reducing weight at the same time. And of course, the Olympus wouldn’t be the Olympus without a sticky Vibram MegaGrip outsole, so you really won’t see more premium materials or ride on any other trail shoe out there. Why stop at 100 miles anymore?
