TREX 6326 Spikeless Traction Devices for boots and shoes reduce the risk of slips and injuries by providing spike-free traction on slick surfaces, particularly oil, grease and water. Powered by Soles by Michelin® (SBM), these traction slings are designed for indoor and outdoor work environments where extra traction is needed and where injuries commonly occur. This device easily fits over work boots or shoes for added anti-slip protection and is ideal for workers who need additional stability but also prefer to wear their own shoe or boot on the job. To achieve superior traction, the soles are constructed with SBM work compound extreme rubber specifically engineered to provide adherence and adaptability on slippery surfaces. The tread pattern is designed to provide constant contact with slippery surfaces and features shallow grooves to disperse water, oil and grease. These slip-on slings will fit over any style of boot or shoe for added traction.
