This pack of Bombas youth socks comes with twelve pairs of the most comfortable socks in the history of feet. We use the softest, most durable cotton, link the toe seam with a special knit stitch to get rid of that annoying bump across the top, and add in a growth guarantee for good measure. If your little one grows out of these socks within the next year, we'll send you a pair the next size up free of charge. One purchased = one donated.
