MEN 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™ 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 Vibram® 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.
