Sock101 (PPAI 625402, Silver) was reportedly the first to introduce fully knitted custom socks to the promo industry back in 2013. The Lee’s Summit, Missouri, company has come a long way from its origins as a Sock of The Month company.

It now offers a wide range of custom products including recycled dress and athletic socks, shoes, apparel and hard goods. Last year the company’s outstanding products, communication and service won it PPAI’s coveted Supplier Star Award.
