Comfort Business Socks feature anti-static and anti-bacterial properties in a medium-light weight. The Comfort Business Sock, with padding on soles, toes and heels, is designed for everyday business wear. They have 28% tencel fibre, which is very similar to bamboo fibre, but it is made from hardwood and maintains its strength much better under moist conditions, which extends the life of the sock without losing that comfortable bamboo feel.
