Sophia Yue Li, a staff scientist at the KITE Research Institute, is spearheading a groundbreaking initiative to reduce winter slip-and-fall accidents with the RateMyTreads program. “We use our WinterLab to test winter footwear under realistic icy conditions,” Li explains. The lab evaluates boots by having users walk on a tilting icy surface while secured in a harness, with the angle of inclination determining the footwear's slip resistance.
The initiative emerged from a larger study aimed at reducing winter injuries. “We developed a scientific method called maximum achievable angle testing to assess the grip of winter footwear,” Li notes. The program’s goal is to provide consumers with data-driven insights, empowering them to choose safer boots.
Science behind snowflake rating
RateMyTreads uses a unique snowflake rating system to help consumers identify the best winter boots. “Two snowflakes are better than one,” Li says, adding that any footwear without a snowflake rating likely doesn’t meet the standard for safe winter walking. The ratings reflect how well boots perform on icy slopes, with higher angles correlating to better grip.
Li highlights the importance of outsole material in providing slip resistance. “Many winter footwear brands now use specialized materials like Vibram IceGrip and ICEFX,” she says. However, the material alone isn’t enough. “The design, hardness, and manufacturing of the outsole all play a role in determining performance on ice.”
To date, RateMyTreads has tested over 800 types of footwear, with detailed results available on its website. “We encourage consumers to not only check our ratings but also reach out to manufacturers to demand safer footwear,” Li urges.
Industry partnerships drive results
The program also collaborates with major organizations to enhance workplace safety. For example, Canada Post uses snowflake-rated boots for its employees and has seen a significant reduction in winter-related fall injuries. “Encouraging workers to use these boots shows clear evidence of the benefits,” says Li.
The initiative doesn’t stop at winter safety. A newly launched “RankLab” focuses on testing non-winter footwear on various flooring materials, aiming to prevent falls year-round. “This research will be invaluable for health and safety officers looking to recommend or procure safe footwear,” Li asserts.
Paving the way for safer winters
Looking ahead, Li is optimistic about the program’s impact. “Our ultimate goal is to ensure people can walk safely, no matter the season,” she says. By blending rigorous scientific testing with consumer education, RateMyTreads is setting new standards for safety footwear in Canada and beyond.
For those seeking to improve their winter safety, RateMyTreads offers an invaluable resource, and as Li puts it, “with informed choices, we can make winters safer for everyone.”
