MERCANTA MIDSOLES provide cushioning and stability. We take extra care in the midsole to ensure that cushioned stability stays constant for the life of the boot. OUTSOLES perform two functions. They withstand abuse from below, yet aren’t so rigid your body “jars” with impact. They also cushion, but not to the point your feet tire out. Urethane We mould our urethane outsoles using a unique formula that puts cushioning and durability in a lightweight boot. Polyurethane A class of versatile polymers that are tough, yet flexible. Provides underfoot comfort, flexibility and slip resistance. Thermoplastic Urethane A class of plastics with many useful properties, including elasticity, transparency, and resistance to oil, grease and abrasion. Rubber Rubber outsoles are abrasion resistant. They are durable enough to last through your longest days and provide excellent resistance to cuts and scratches. Crepe This cellular rubber gives you the durability of traditional rubber with less weight so your feet and legs don’t tire as the day goes on. Vibram® Exceptional design intersects with innovative rubber compounds to create versatile, performance outsoles. Vibram® outsoles offer excellent traction and high abrasion resistance in a multitude of environments. RW Super Sole® Single density urethane sole designed to provide durability and comfort. lt delivers performance factors of abrasion resi- stance, cut resistance, traction, and oil and chemical resistance. RW SuperSole® 2.0 Dual density urethane sore designed with inner sole to provide cushion and comfort, and outer sole to provide durability and protection. This premium sole not only provides top performance in traction, abrasion resistance, cut resistance, oil and chemical resistance, but also delivers maximum comfort. Slip Resistance A key feature in soles. All soles are tested for traction based on the wet average of Mark II & SATRA tests. This is a measurement of friction on wet quarry tile. The greater the friction, the greater the traction. Oil/Gas Resistance Resists swelling of the sole from absorption of oil and gas. Chemical Resistance Resists acids and caustic chemicals. Abrasion Resistance Resists abrasive surfaces like gravel, concrete & asphalt. Heat Resistance Resists melting at a minimum of 475° Fahrenheit (246° Celsius). Soles that have been designed and tested to perform on high heat surfaces. Soles identified as HRO are heat resistant to melting at a minimum of 475° Fahrenheit. Non-Marking Does not leave marks on non-abrasive flooring surfaces. Steel Made from one of the most durable and dependable materials on earth. Red Wing uses steel shanks to support your feet. Lineman Wider than traditional steel shanks, it is designed to provide extra strength and support to withstand the rigors of climbing. TC TechTM / H-Tech Plate Provides lightweight torsional stability with an anatomically contoured shank plate. This component is an integrated piece of nylon designed with a solid instep area for multi-directional strength and a series of „fingers“ that extend toward the ball of the foot to allow flexibility. 227
