Taken from the SmarKnitKIDS website:
Tired of hearing her son scream “these sock seams keep bugging me,” a mom decided something needed to be done. Every “seamless” sock her son tried had seams in it; there was not a truly seamless sock available. After explaining the frustrating morning routine to countless friends of her son’s struggles with socks, she was finally given the name of Knit-Rite, a textile manufacturer, and contacted them with her request for a seamless kids sock. After several requests for seamless socks from "desperate" parents, SmartKnitKIDS socks were created.
Knit the same way a caterpillar spins its cocoon, SmartKnitKIDS socks are started at the toe and worked up toward the ankle. This process insures a 100% seamless sock, so there are no seams to bug ya! A form-fitting design also keeps those annoying lumps and bumps out of the socks.
Since its launch in 2003, SmartKnitKIDS continues to find new markets and grow every year. Super soft material and a seam free design make it the most comfortable kid’s sock on the market. SmartKnitKIDS come in a color for every personality: white, black, pink, purple, and navy. Ankle, crew and knee-high styles are available up to a youth size 8.
