Adjustable Sprint Shoe

The adjustable sprint shoe was designed for junior athletes. Each shoe can be adjusted to fit up to three sizes. This allows the athlete to adjust the shoe to fit them, whilst their feet continue to grow. The athlete is then able to use their favourite shoes for longer avoiding having to throw away hardly worn shoes. This increases the lifespan of the shoe.
The adjustable sprint shoe can also optimise the performance of the athlete because it has no heel, which reduces the weight by 20 percent. The sole of the shoe was inspired by the paw of a cheetah, the fastest animal on the planet.
