One entrepreneur has dreamt up a simple fix to an age-old problem: the constant need to buy new shoes for kids who outgrow them just months later.
American charity worker Kenton Lee and his team invented sandals that match the pace of children's growth via a system of buckles, buttons and pegs, which expand the shoes in length by up to five sizes. Build to last at least five years, they are made out of durable leather, metal snaps and compressed rubber.
