All Sport Socks

Our sport socks are made from cotton blends, merino wool, and specialty copper-infused yarns. Cotton blends offer breathability and comfort, merino wool provides temperature regulation and moisture control for outdoor activities, and copper-infused yarn is knit directly into the sole for lasting odor and circulation benefits.

Yes, our copper-infused socks use copper ion yarn knit into the sole that won't wash out over time. They help improve circulation with a non-binding top, inhibit foot odor and athlete's foot, wick away moisture during activity, and include arch support for reduced fatigue during long training sessions.

Yes, our King Size Socks Collection is specifically designed for shoe sizes 12-15 US, including quarter sports styles, merino wool crew socks, and therapeutic HealthTrak options. These are built with the same cushioning and durability as our standard sizes, just tailored for larger feet.

No-show socks sit below the shoe line for a hidden, low-profile look ideal for sneakers. Quarter socks extend slightly above the ankle for added protection while staying low-cut. Crew socks rise higher up the calf, offering more coverage and cushioning, often preferred for running, hiking, or cold-weather activities.
