It is safe to use it in snow removing work after snowfall or in freezing of snow and road.
Because it can be used for light climbing such as trekking, the application is wide.
Because it is made of rubber and stretch is also good, you can use it for men's business shoes, boots, trekking shoes that have the same size even if the outer size is larger.
Because it is made of rubber, consider it as a consumable item to some extent. I will recommend spare stand-ups so that they can cut anytime.
