Features

1. Strong and socklike FirmaKnit™ uppers are made from 99% recycled PET polyester and are designed for lightweight yet durable comfort right out of the box
2. HydroWall™ complete waterproof/breathable protection keeps your feet dry when the trail ahead isn't—and uses 75% recycled polyester to do so
3. 20% recycled rubber TerraGrip™ tread provides anti-slip grip on all kinds of terrain with 4 mm forefoot climbing lugs for going up and 4 mm heel braking lugs for coming down
4. TerraLoft™ midsoles use 10% algae-based BLOOM™ foam to cradle your feet with a cushioning system that feels like your favorite trail-running shoes (soft, but not too soft)
5. TrailBed™ insoles use Insite® Contoura® technology created with podiatrists to ensure support and comfort; plus, it's made with 25% USDA-certified bio-based Susterra® compound
6. 2-layer 30% recycled TPU overlays are designed to create durable and supportive uppers—the structure you need for long hours on the trail that's still light and minimalist
7. Molded nylon midfoot shanks provide lightweight support to protect your feet from the trail and help propel you forward
8. Recycled PET polyester webbing and lacing creates a midfoot cradle system that allows for a highly adjustable and locked-down fit
9. Extra space in the toe boxes allows for natural changes in your feet (like swelling) during hours of trail exploration
10. Informed by feedback from over 6,000 people and field tested by 100 co-op members over 2,000 hours and 700+ miles
