Expandables tackle two challenges at the same time, accessibility of shoes for kids in underserved regions and the fact that kids outgrow their shoes in rapid speed. Over 1.5 billion people suffer from soil transmitted diseases worldwide. Without shoes, children are especially vulnerable to soil-transmitted diseases and parasites that can cause illness and even death. The Shoe That Grows can change that in a sustainable way. During a growth spurt, kids can outgrow a pair of shoes in just a few months. Expandables tackle growth, durability and sustainability. Expanding + Sandals = Expandals
