SATRA innovation helps to counteract rotational slip forces

Explaining the science behind rotational slip in footwear and highlights a new SATRA development that can help to reduce the risk of ligament injury to the wearer.

Conventional slip resistance refers to the translational movement between the shoe and the ground. Slip resistance is necessary between the sole of the shoe and the flooring surface in order to minimise the risk of slipping, with the level of resistance produced specific to the footwear’s purpose. Too much resistance can result in a blocking action (when the movement of the soling suddenly stops), and too little will result in a slip – both of which can lead to injury. The ability to control the level of slip resistance is of significant importance with respect to both translational and rotational (torsional) slip. SATRA is developing new techniques in line with this ongoing area of research.
