No ordinary shoe laces; put them in sunlight and - Whoa! - these funksters change colour!
Yep, these laces are unassuming white when indoors, but take them outdoors and, magically, a colourful design will appear, even on cloudy days.
UV light activates the photochromic ink on the laces, inducing the reversible colour change. Back indoors, away from UV light they change back to white again. A great reminder to stay out of the sun!
These laces come in two fantastic designs - pretty pink butterflies and awesome blue dinosaurs. Choose your preferred design from the drop down menu above.
Say goodbye to boring sneakers with these sure-fire playground hits!

How Does It Work?
The printed design on these remarkable laces contain an ink base that changes colour in sunlight. Special pigment in the ink reacts with UV light, changing the shape of the pigment's molecules and hence their colour. This light induced chemical reaction is called photochromism and is reversible. When the coloured laces are bought indoors and away from the sun's ultraviolet rays they change back to off white. They can change colour thousands of times, and the laces can even be washed without any noticeable impact on the colour change.

- Photochromism: a light-induced reversible change of colour
The stronger the UV radiation the more intense the colour change. The photochromic ink does not react to ordinary house lights - the light must be UV.
