Ever wonder how different winter boots measure up in a slip test? Scientists at the Toronto Rehabilitation Institute devised a test to give winter boots a traction rating.
Researchers had volunteers walk across ice at various angles. In all, 90 of 98 boots failed a slip test on surfaces up to a 7-degree angle—the slope of a handicapped ramp.
Learn more, including which boots pass the test and tips for how to walk safety on ice, in a video from Scientific American.
