Cristiano Ronaldo Uses Black Toenail Polish for Athletic Protection

Cristiano Ronaldo has been seen with black nail polish on his toenails for several years, a practice that fans recently noticed again in a photo with his son Cristiano Jr. The black polish is not a style statement but a practical measure to protect his toenails from fungus and bacteria, which are common issues for athletes who spend extensive time in sweaty shoes. This method, popular among combat sports athletes like Mike Tyson and UFC star Israel Adesanya, hardens the nails and prevents cracking or splitting under physical stress. Ronaldo's use of black toenail polish fits his well-known dedication to maintaining peak physical condition through rigorous health and fitness routines, including a protein-rich diet and multiple daily naps. The protective coating helps him manage the demands of playing professional football at an elite level even at age 40. This small but significant detail highlights Ronaldo's relentless discipline and innovative approach to longevity in sports.
