Hobnail boots became well-known during and after World War II because they were the preferred boot used by the German army. Hobnail boots were also popular with climbers and mountaineers who used them to provide traction in loose rock, ice and snow. A heavy duty, hard-wearing work boot with hob nails in the sole makes them last longer and provides grip on muddy ground. These Roman Army Iron Boot Hob Nails are made of iron and have a cone shaped head with spiked tips. This set includes 100 pieces which will provide repair and durability to more than one pair of boots.
