Several work shoe brands have developed special inlay soles for their shoes. These can be easily placed inside the shoe and will stay stable and in place thanks to a anti slip underside. Soles in safety shoes offer more benefits: most are anti-bacterial, odorless and dry very quickly. The most important feature may be the extra attenuation the soles offer against (extreme) vibrations.
The work sock has roughly the same purpose as the soles: offering your feet extra support. Work socks are strengthened where necessary. Usually in places where the shocks are hardest or where the socks will first start to wear. There are also socks manufactured with extra wool. These are perfectly suitable for colder periods of the year or if you work in cold spaces a lot.
