If the region in which it inhabits is not very cold winters, it may be convenient to accept means that can be mounted on wheels whenever necessary: socks and snow chains are best known.

As you can guess from the anecdote shirt, snow socks have the advantage of being very easy to handle, easily and quickly to assemble.
