The best inventions are the ones that solve a common problem in the simplest way possible. A lot of times, seeing such an idea makes you wonder how nobody else ever thought of it until now. Inventor Kenton Lee’s sandal, called “The Shoe That Grows,” does all of the above.

Anyone with children can tell you that one of the most irritating experiences for parents is having to constantly re-purchase clothes/shoes/etc. because kids outgrow them so quickly. The Shoe That Grows features an innovative adjustable design that allows it to expand up to five sizes and last at least five years.

Children without shoes are susceptible to a variety of injuries and a host of parasites and infections that can enter through the feet. According to The Shoe That Grows, there are over 300 million children worldwide who do not have adequate footwear. While regular shoe donations help, these shoes are quickly outgrown, which is precisely what these shoes hope to address.

If you’re interested in buying a pair for yourself or (hopefully) buying some shoes  to send to a child in need, please head over to the company’s website. You can even buy in bulk, which can bring the price (per unit) down by over 50% while simultaneously making a lot of kids very happy.
