BUILT FOR THE TRAIL BUT ANSWERS TO THE CALL OF THE RUN. The Cascadia 8 was designed from the gritty, wet, and uneven ground up. engineered to adapt to the surface and your foot, this versatile piece of equipment runs an ultramarathon and then asks for more. we swapped out the midsole for BioMogo DNA to create a super cohesive transition and deluxe-ified the Caterpillar Crash Pad on the lateral side to smooth that heel-to-toe even more. the suede geometric pattern on the upper is a shout-out to past Cascadia designs but also serves the function of wrapping the foot for a close fit.
