The Thorlo 12 Hour Shift OTC Work Sock is a unisex 12-hour shift thick-padded over-the-calf work sock knit by Thorlo in their Statesville, North Carolina mill. Activity-specific engineered cushioning places extra padding exactly where it’s needed for that activity — forefoot for running, heel and ball for tennis, full-foot for combat boots — and removes bulk where it’s not.
Use it for long shifts in work boots, military and tactical duty, construction, ranch and farm work. Thorlo’s clinical research-backed designs are recommended by podiatrists and orthopedists for foot-pain relief, and the brand is the official sock of the US Tennis Association and various US military units.
Thorlo has been knitting performance socks in Statesville, North Carolina since 1980. Every Thorlo sock is American-made and engineered for a specific activity.
