Slip resistance is measured in many different ways around the world. Published results can often be very misleading and inaccurate when related to “real world conditions”. All our footwear meets & surpasses SRC rating under the commonly used ISO EN20345:2011 but this is a very basic minimum requirement so we go much further by testing to a new Grip Rating Scheme developed by the UK Health & Safety Laboratory.
This test involves the use of a ramp which can be increasingly tilted until the person walking on it slips. A measurement, called the Coefficient of Friction, is taken at the point of slip and after a number of repeated tests involving different people, an average is determined and a “star” rating awarded to that footwear. Suregrip achieved 4* and Grip Wellingtons 5* which in simple terms means they will grip even on oily or greasy surfaces. Our new range from S R Max however easily achieved a 5* Grip rating on all products and will start to replace previous styles over the coming months
Slip resistance isn’t all about pure grip levels however; footwear must have a level of durability & wear resistance so it goes on working long after the initial issue. S R Max outsoles typically last twice as long as other brands & go on achieving 5* performance throughout their life. It is important to be aware that not all outsoles can do this & often reduce to 2* or less after just a few weeks wear. It is important to understand these subtle differences in order to make the correct choice of footwear.
