microspike
Microspikes are a type of traction device designed to be worn over footwear, typically hiking boots or shoes, to provide increased grip on icy or snow-covered surfaces. They consist of a rubber or elastomer harness that stretches to fit over the sole of the shoe, attached to a metal chain or wire system. This chain or wire is embedded with small, sharp metal spikes, usually made of hardened steel. When a person walks on ice or hard-packed snow, these spikes dig into the slippery surface, preventing slips and falls.
The design of microspikes offers a balance between aggressive traction and the ability to walk on less
Key features of microspikes include the material and length of the spikes, the type of harness used
