Cristiano Ronaldo, one of the most disciplined and popular athletes in the world, has once again attracted attention with a habit: painting his toenails.
According to German newspaper BILD, the 39-year-old practices this action for hygienic and protective reasons, preventing bacteria and fungi that can appear due to sweat on shoes.
This habit is not unknown among professional athletes, especially in sports like boxing, MMA, and athletics.
Big names like Mike Tyson and Israel Adesanya have used the same practice throughout their careers to maintain high-level foot hygiene.
In addition, Ronaldo is known for his extreme dedication to his health and fitness. He uses the Oura Ring, a smart bracelet that monitors sleep, temperature, heart rate and physical activity, as part of a detailed routine that includes up to five naps a day.
