The NFL reportedly announced it would be loosening its dress code in a memo on Tuesday, according to Darren Rovell of ESPN.com, as "players will be allowed to wear more personalized cleats for pre-game prior to warm-ups and will have greater flexibility on cleat color worn during the game."
Rovell added, "During pregame warm-ups, players can wear any design they want, so long as it doesn't depict commercialized or trademarked logos, other than the league-approved footwear brands (Nike, Under Armour and Adidas). The cleats also can't have anything that would be deemed offensive or express political views.
