AEGIS Microbe Shield®
AEGIS Microbe Shield® acts to control the bacteria, algae and fungi that cause odors, stains and deterioration. AEGIS is odorless, colorless, free of environmentally harmful substances, does not dissipate or leach, and will remain effective as long as the surface of the treated area remains intact.
Aegis Microbe Shield™
Closed-cell ‘neoprene’ lining with hydrophobic nylon cover impregnated with the anti-bacterial, anti-odor agent Aegis™.
Aegis™ Hydrophobic SBR
(Styrene butadiene rubber.) Closed-cell ‘neoprene’ lining with hydrophobic nylon cover impregnated with the anti-bacterial, anti-odor agent Aegis™.
Anatomical Flex Fit
Machines knit counter-clockwise to give sock a seamless fit that bends to feel comfortable and to contour the foot.
The true shape of the foot is incorporated into the fit of Keen sandals, with lasts designed in-house by casting multiple feet to achieve perfect volume and shape.
Carbon sticky rubber outsole
All Keen soles are non-marking with a patented toe guard, offering good grip, flex, durability, and protection for the toes.
Compression-Molded EVA Footbed
Provides comfort, cushioning, and odor-free sandals with the antibacterial agent Aegis™ in a microfiber top cover on firm ethyl vinyl acetate.
Using no adhesives, the direct-attach method of construction fuses the sole to the upper, offering a superior, water-resistant bond and extending the life of the shoe or boot.
Dri-Lex® technology combines hydrophobic (moisture-hating) polyester and hydrophilic (moisture-loving) nylon to create a dual-zone, moisture-wicking, abrasion- and bacteria-resistant environment.
Dual Climate Rubber Outsole
Adjusts by hardening in cold temperatures and softening in warm temperatures, offering superior traction in less than ideal conditions.
Electrical Hazard Protection
Meets ANSI Z41 PT99 standards for electrical hazard protection from open circuits.
Provides exceptional torsional stability for a secure ride.
A waterproof membrane allowing moisture from sweat to pass directly through millions of tiny open pores and to the outside of the fabric. Outside water is unable to enter, in turn keeping you dry and comfortable.
Goodyear® Welt Construction
In this superior method of footwear construction, a strip of PVC or leather is stitched to the edge of the upper and the sole is then attached to the welt by a heat welding process, creating a highly durable, flexible design in shoes and boots.
KEEN's Heat Trapolator consists of three innovative heat-trapping layers—a honeycomb top layer, a wool insulation layer and a thermal heat shield—to hold warm air inside the shoe or boot, similar to the functioning of building insulation.
A true underfoot insulation system designed to provide exceptional comfort in cold weather.
This urethane-coated leather will not harden or crack after drying or with repeated exposure.
This full-length plastic (TPU) stability plate combines forefoot flexibility with the stability you need on the trail or at the jobsite.
KEEN Topo Foam
Used in backpacks and daypacks, KEEN's perforated mesh-covered EVA foam is molded into peaks and valleys, enhancing air circulation to keep the wearer cool and comfortable.
KEEN ZORB Strobel
Stitched to the KEEN metatomical footbed, KEEN ZORB enhances spring, absorbing greater shock with every step.
KEEN.Connect footwear is characterized by a low profile designed to allow the foot to move naturally. Styles in the CNX collection employ a KEEN classic fit that has been modified to have a more secure heel and slight reduction of width and volume. Minimal upper construction eliminates layers of material for an improved fit and reduced weight. A metatarsal ridge and integrated, contoured arch provide natural underfoot support. These shoes also feature a lightweight polyurethane midsole, stability shank for added support, 4mm heel-to-toe offset for natural foot movement and have multi-directional flex grooves in the sole for a better connection with varied terrain. All KEEN.Connect shoes weigh 10 ounces or less.
Keen takes an eco-conscious step by using cork – a renewable, natural, sustainable material. Cork cushions offer shock absorption.
This footbed is made of recycled polyurethane, cork, and memory foam to contour to the foot.
The Dual Climate Rubber outsole hardens in cold weather for traction on packed snow.
KEEN.DRY Waterproof Membrane™
The KEEN.DRY Waterproof Membrane™ is a waterproof, breathable membrane that lets vapor out without letting water in to keep feet dry and comfortable in cold, wet conditions.
KEEN.DRY™ Waterproof Membrane
The KEEN.DRY™ waterproof membrane is a waterproof, breathable membrane that lets vapor out without letting water in to keep feet dry and comfortable in cold, wet conditions.
Oil- and slip-resistant outsole that meets or exceeds ASTM (American Society for Testing and Materials) F1677-96 MARK II non-slip testing standards.
Combining functional design and an innovative shape, KEEN.PROTECT keeps your toes safe from the unexpected.
KEEN.WARM is a lightweight, sustainable, anti-microbial insulating material that keeps cold air out and body heat in for warm feet, even in cold temperatures; the material is made partially of charcoal bamboo.
KEEN's own welted construction offers enhanced durability and flexibility, extending the life of the boot or shoe.
Stitched to the KEEN footbed, KEEN.ZORB Strobel insole technology combines a cushioning foam layer with minimal seam construction. It enhances comfort, absorbing shock and adding spring to every step.
Sock is cushioned along the entire foot bottom.
Meets ASTM standards
Meets American Society for Testing and Materials (ASTM) F1677-96 Mark II non-slip testing standards.
Metatomical Footbed Design
KEEN's metatomical footbed design is an internal support mechanism that cradles the foot and provides excellent arch support.
This non-toxic topsole treatment uses small amounts of zinc powder, a naturally occurring microbe inhibitor, to reduce odor-causing bacteria.
Sock is cushioned from the top of the welt to the toe.
Patented Toe Protection™
Combining functional design and an innovative shape, KEEN Patented Toe Protection keeps your toes safe from the unexpected.
PrimaLoft® is a lightweight, breathable, and insulated lining, rated to –25° F.
A synthetic microfiber insulation that is lightweight, repels water, and maintains warmth in wet conditions.
Maximizes sensitivity to terrain while providing adequate forefoot protection.
S3 stands for shock, suspension, and stability. This supportive technology is engineered to support the foot on impact, dissipate shock and reduce the odds of twisting an ankle.
S3 Heel Support Structure
Supports the foot on impact by dissipating shock, stabilizing the ankle to prevent roll.
SATRA-Certified Anti-Slip Sole
This shoe is deemed suitable for work in slippery environments. Slip-resistance tests have been carried out by SATRA, the world's leading research and technology organization for the footwear industry.
Shellback™ Heel Support
Made of molded rubber, Shellback™ provides a rigid platform, adding stability to a range of winter activities.
Waterproof leather, nubuck, or synthetic upper material, designed for use in or out of water.
Thermal Heat Shield Footbed
A three-layer system that keeps feet warm, comfortable, and dry. On the outside, wooly softness. In the middle, EVA for support and cushioning. Inside, a thermal heat shield to keep cold out and heat in.
Sock is cushioned in the toe and heel.
A rubber compound that is highly resilient and durable. Reduces shock upon foot strike and reduces foot fatigue.
Wishbone Strap Technology
Wishbone yoke straps help distribute the load across the shoulders for added comfort; an adjustable, detachable sternum strap also aids in weight distribution. Shoulder straps are dual folded for added comfort, and wrap around the body for a contoured fit.
