Five generations in and the legacy of unstoppable comfort continues. We kept the beloved 35 mm x 30 mm stack height but tweaked the ZipFoam(TM) midsole to bring you a new design while keeping the plush, responsive ride Ultraventure is known for. From trail, to gravel, to road, the trusted VibramA(R) XS Trek outsole features an intentional lug pattern and depth built for optimal all-terrain performance. The mesh upper delivers our signature fit with increased durability, now updated with our universal gaiter system.
