Soft Flex – 2 (1-10 Rating System)

Backstays – Tough Surlyn material, anatomically shaped and 3-D molded heel reinforcement to provide an even boot flex and long lasting support.

Articulating Cuff – The upper cuff of the boot is asymmetrically connected to the lower boot allowing the ankle to flex naturally while providing support without shell distortion.

Asymmetrical Design – New for 17/18 is the asymmetrical Boa® lacing and boot design for targeted medial support and even forefoot closure.

Comfort and Fit – Flow's proprietary and anatomically shaped inner and outer lasts.

3-D Molded Tongue – Anatomically correct to provide less bulk and a true natural flex without boot distortion.

3-D Molded/Lasted Toe Box – Eliminates extra layers and seams around the tip of the boot and creates a durable streamlined design with less bulk and a better fit.

1-Feather – An integrated lacing liner and internal J-Bars add support, while 3-D molded EVA, a custom flex zone in the forefoot and a soft, die-cut EVA insole improve fit and add cushion.

Integrated Lacing Liner – Lace pulls are directly integrated into the liner and stitched webbing for support.

BOA® – Gram for gram, the Boa® lace is stronger than tank armor. The Boa® Closure System provides quick and easy custom comfort with a smooth, even closure and no pressure points. Boa® components are guaranteed for life.

Molded EVA – With the dual density EVA foam molded into the anatomical shape with a deep heel cup and arch support, the forefoot gets more Kush for flexiblity while the arch and heel remain more supportive. A silicone screen print provides added traction.

Thermo-Lite – A blend of lightweight rubber compound that makes for a durable, lightweight, and performance driven outsole.

Spaceblanket Insulation – a thermal insulating barrier between the outsole and the liner, which keeps the heat inside and the cold outside.
