PORLAND, Ore., (Oct. 8, 2021)KEEN Inc. (KEEN), the footwear brand on a mission to make  the outdoors inclusive and accessible to all, is proud to announce its popular Revel IV Polar  men’s and women’s boots earned the prestigious snowflake rating from Canada’s KI TE  Research Institute, rating footwear for its superior ability to prevent unintentional slips and falls  in the icy conditions of Canadian winters.  

KEEN’s Revel IV Polar men and women’s boots provide the agility of a hiking shoe, coupled  with the warmth of a puffy coat. Built for active, frigid days, this boot is constructed of  waterproof, durable leather and high-performance mesh. The Thermal Heat Shield, combined  with 200g of KEEN.WARM Recycled PET insulation, protects feet up to -25F, while a  KEEN.DRY waterproof, breathable membrane and ECO Anti-Odor control keeps feet dry and  minimizes odor.  

“The KEEN Revel IV Polar boots were specifically engineered to deliver more warmth and  traction, without the bulk. They’re rated down to -25F and the KEEN.Polar Traction outsole  means they’re exceptionally grippy on snow and ice,” said Keith Denny, Sr. Director, Product  Management. “It’s cool to be awarded this rating in Canada – they know what it takes to be  comfortable during harsh winters.” 

The snowflake rating is bestowed to footwear that has the best in class design and technical  features that help prevent slips and falls in the worst possible icy environments. Only 33% of  footwear tested by the KITE Research Institute to date have received this accolade.  

“Canada has some of the iciest terrain in the world and our ratings system is built to test the  limits of these conditions and help consumers find the highest-performing footwear on the  market,” said Dr. Geoff Fernie, Senior Scientist at UHN’s KITE Research Institute and the  Creaghan Family Chair in Prevention and Healthcare Technologies. “The KEEN Revel IV Polar  boot was awarded one snowflake following rigorous testing in our WinterLab simulator using the Maximum Achievable Angle Test (MMS). This achievement signifies a safe and effective quality  boot that provides slip resistance that can help conquer Canadian winters.” 

 The KITE Research Ins titute is the research arm of the Toronto Rehabilitation Institute at the  University Health Network. One of the institute’s priorities is to help prevent slip-and-fall  accidents that can affect a person’s mobility and quality of life. The Institute rates footwear by  putting shoes through comprehensive testing in its revolutionary WinterLab; a unique simulator,  where ratings are awarded based on positive outcome in their Maximum Achievable Angle  (MAA) Test[JB3] .
