Soule / Shoe

Soule
Soule

Soule is a shoe that tells the story of where you are and where you have been. The colors of the shoe are influenced by rain, snow and surface waters. Every time the shoe gets in contact with water new color combinations will appear. The shoe is created using chemical compounds called indicators. I developed a paint out of these that makes the shoes respond to the acidity levels of water. The stripes on the shoe change color once they have reached a tipping point, and can also change back to the original color. The shoe will continuously have new color combinations, corresponding to the pH of the water it was last in contact with.(they work)
