Color Changing Laces
SR4U Color Changing Laces start out as white until you go outside. When the laces are exposed to the sunlight they will transform into another color right before your eyes. When going indoors or into the shade they will transform back to white. Available colors are Yellow, Pink and Purple.
Laces are suitable for all soccer/football boots including Superfly, Obra etc and are 100% Polyester, 47 inches or 119 cm in length.
