Features

  • 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
  • HydroWall™ complete waterproof/breathable protection keeps your feet dry when the trail ahead isn't—and uses 75% recycled polyester to do so
  • 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
  • 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)
  • 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
  • 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
  • Molded nylon midfoot shanks provide lightweight support to protect your feet from the trail and help propel you forward
  • Recycled PET polyester webbing and lacing creates a midfoot cradle system that allows for a highly adjustable and locked-down fit
  • Extra space in the toe boxes allows for natural changes in your feet (like swelling) during hours of trail exploration
  • Informed by feedback from over 6,000 people and field tested by 100 co-op members over 2,000 hours and 700+ miles
  • REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
