In the modern world, we don’t need to worry about worn out shoes. They get too worn out and you just go to a Foot Locker or Walmart and buy a new pair. But what happens when these stores no longer exist and you have to make your own shoes? Agy from Green Issues shows us how to make a pair of flip-flops out of old t-shirts. All you need is a t-shirt, some string, and some glue. With a little ingenuity, you could probably improve on the design and make full blown shoes!
