Sure, we imagine Reigning Champ could have done it themselves, but they definitely would have their work cut out for them with brands like Stance on the market. The athleisure experts have teamed up with the popular sock brand on a collection of three essentials: Athletic Crew Socks, Super Invisible Socks, and Boxer Briefs. The socks feature terry cushioning and a seamless toe closure design while the underwear uses soft Supima Cotton and Feather-seam no stitch construction for enhanced comfort.
