An anti-slip device is a device used to prevent slipping or sliding on a surface. Two common examples of anti-slip devices are cleats and mats. Cleats are small metal or plastic spikes that are attached to the bottom of shoes to provide traction on slippery surfaces. Mats are flat pieces of material, usually rubber, that are placed on the floor to provide a non-slip surface. Both cleats and mats are effective anti-slip devices that can help reduce the risk of slips and falls.
