Fly over trails in the waterproof, breathable men's REI Co-op Flash hiking boots. REI-exclusive technologies create fast-and-light boots—with a lighter footprint—that are comfy right out of the box.

  • 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
