SUPRAFLEX™: Flexible Thinking in Boot Design

Flexible Thinking
in Boot Design

Introducing Supraflex™

Our state-of-the-science boots with segmented flex panels. Because scientific studies have proven that lighter weight and more flexible footwear isn’t just about comfort – it’s about safety.

SUPRAFLEX™ performs like a boot. Feels like a sneaker.

ATHLETIC FOOTWEAR CONSTRUCTION

Two-part cross-linking adhesive bonds outsoles to the upper. Without stiff welts and ribbed mid-soles, this attachment process is far more flexible.

CONTINUOUS SEGMENTED FLEX PANELS

Throughout the front of the shaft and top of the foot to provide unprecedented flexibility to make these boots feel like your favorite pair of athletic shoes.

RECESSED SIDE PULL-ON HANDLES

Integral pull-on handles are inset on the sides and hidden when not needed.

GORE® CROSSTECH® FOOTWEAR FABRIC

A full-height bootie liner made from a package of Omaha lining fabric, 300g insulation, and GORE® CROSSTECH® moisture barrier provides protection unmatched by any other waterproof, breathable barrier.

ADVANCED COMPOSITES

Composite puncture protection, safety toe cap, and shank are stronger than steel and don’t transmit heat or cold.

VIBRAM® OUTSOLE & SLIP-RESISTANT TREAD

Molded outsole wraps onto leather upper for athletic shoe performance. Flame, abrasion, oil, acid and slip-resistant compound engineered for high traction and durability. Optional Arctic Grip Pro outsoles.
