Humans often climb up and down hills, and many times end up falling if the hill is too steep. Squirrels are able to climb up and down trees with no trouble, so how can humans climb up and down steep hills without trouble? The boot was designed to prevent falls while climbing up and down steep hills. The boot mimics that of a squirrel, which uses both front and back claws to anchor into a tree. Squirrels are able to climb down a tree head first by rotating feet and using its claws.

This model was created for humans to use to climb hills and also go down hills without falling. This model mimics the claws of a squirrel. The metal in the bottom of the removable sole acts as an anchor and gives traction while going up or down hills. The metal is like the claw of a squirrel in which it acts as an anchor to the ground to prevent humans from slipping while going up or down a hill. The first design was metal coming out of the boot in a hook shape, which would act as the anchor. The newest design is a removable sole that has metal on the bottom of the sole. The metal will still act as an anchor to the ground as the human goes up or down hills. The purpose for metal being at both the front and back of the sole is to provide the traction for both going up and down hills.

This drawing shows that the metal is still at the bottom of the boot but it is removable so it can be used on any shoe.

This drawing shows that that metal was moved to the bottom of the boot to help with traction.

1. A squirrel turns its back feet around 180 degrees to help climb up and down trees. This can be used to help humans climb up and down hills without falling.
2. A squirrel buries nuts and seeds, in which most of the time will result in more trees. This helps humans have more resources.
3. Squirrels use their tails for communication, balance, and protection.

Squirrels spend much of their time in trees or on the ground. Squirrels often climb trees to find food, shelter, and hide from prey. Squirrels use their claws as an anchor as they climb up or down the tree. Their claws allow them to grip to the tree without falling. Squirrels use their back claws to anchor to the tree while climbing down. Squirrels climb down trees head first, unlike many animals. Squirrels have very flexible ankle joints which allow them to turn their feet 180 degrees to anchor their claws into the tree. When squirrels rotate their feet 180 degrees, it looks like their feet are backwards. The reason squirrels are able to rotate their back feet is to have grip as they climb down a tree head first. The design that was created is an adaptation for humans as they climb up and down hills.
