This discount is kinda complicated, but it's good. Trust me. The low-impact route gets you Buy One Get One 50% Off shoes plus an additional 15% off with code SOCKS54. That's slick in its own right, but if you sign up for FF's reward program (free) and use code SOCKS57, they'll give you an additional 20% off. The choice is yours, but you can't go wrong in either case if you're shopping for kicks from Nike, Converse, Vans and more. This all ends tomorrow.
