Slip resistance - Coefficient of Friction (COF)
In terms of shoes, slip resistance is the amount of resistance the sole of the shoe exerts while moving over a particular walking surface. This is measured on a scale based on the Coefficient of Friction (COF). This scale starts from 0.00, comparable to ice, oil or a similar slippery surface and goes up to 1.00, which is like walking on a dry carpet. Industry experts consider a reading of 0.40 to be the benchmark for a shoe providing above-average slip-resistant qualities.
The following tests were conducted on the kybun sole using a standard red quarry satra tile (combined test results):

*These tests (according to ASTM F2913-19 Standards) were undertaken by Precision Testing Laboratories USA, an independent and renowned international company in the field of textile tests.
How dangerous are slippery surfaces?
Tips to help avoid accidents:
- Choose suitable footwear outdoors as well as indoors.
- Always allow enough time for your journey.
- Keep fit with balance exercises as well as strength, endurance and flexibility training.
- From the age of 50, practice balancing in daily routines, e.g. brushing your teeth on one foot
- Use snow- and ice-free paths whenever possible.
