Injinji is a San Diego-based company in the sporting goods manufacturing space, founded in 1999. It developed the Original Performance Toesock, a five-toe sleeve that is seamless and designed to minimize friction, allowing the foot to move naturally inside any shoe. The socks are aimed at runners and active outdoor enthusiasts seeking comfort and performance as they train or compete. The products are sold primarily through run and outdoor specialty retailers in the United States, with a strong ecommerce presence and distribution in 54 countries worldwide. Injinji positions itself as an innovator within the niche of performance socks, focusing on individual toe design to address foot movement and friction during activity. In 2025 it expanded its product offering with the Trail Midweight Over the Calf toe sock, broadening protection and coverage for trail runners.
