Why does Ronaldo always have black manicure on his feet? There Is a Good Reason

Because the footballer publishes frequent photos from the gym, fans have noticed something strange in his posts.

In multiple photos, followers have found Ronald to do his nails in black manicure.

Now, what appears to be a scientific trick behind this.

According to the German newspaper BILD, the reason athletes like Ronaldo choose to dye their toenails is to prevent a moldic infection after spending hours wearing sweat shoes.

It is believed that color adds a protective coat that prevents bacteria from entering the skin.

It has also been suggested that color makes it more difficult for nails to break or divide during training, something Ronaldo is unlikely to realize would have happened because of his shoes during his physical activity. /Telegraphy/
