Free shipping on all orders $50 and up! The Standard hits your calf just below the calf muscle and was specially designed to be worn while working out or hanging out. Our socks are knit-in and engineered with features that provide maximum comfort, durability, and performance as seen below. The Standard is made from an optimal blend of 54% polyester, 20% acrylic, 20% nylon, and 6% wool. Why are our socks acrylic-based instead of cotton or nylon? Acrylic sock fabrics are moisture-wicking and retain their shape better than cotton, preventing that dreaded slippage. They're the perfect fiber to keep your feet moisture-free and happy all day long, no matter the activity. Cotton, on the other hand, does not have moisture-wicking qualities and dampens quickly. When trapped in a shoe, this damp sock can cause a lot of discomfort (and blisters). Why not Nylon? Though durable, nylon socks aren't known for keeping feet odor-free. You and your feet get the picture. Fair warning you and your feet may become addicted to our socks.
