Pointe shoes are crucial when it comes to ballet. They are used all the time! Pointe shoes help ballet dancers push up and dance on their toes. They are commonly known to cause a lot of foot and toe pain. This can easily lead to fatigue on the foot and affect a dancer's performance. It can also lead to injury because when a dancer is in pain and exhausted, it becomes harder to dance and the dancer can get greatly injured. Luckily, these pointe shoes are a modified creation that improves a dancer's performance and safety. It provides extra comfort to minimize foot pain while giving the dancer support by helping to lift them up. The materials used are very simple materials that can be found easily and it can relieve a dancer from foot pain. This creation focuses on decreasing discomfort in the foot which translates into better performance and reduces injuries. There is a lot of focus on the bottom half of the shoe so that this creation can help the part of the foot that experiences the most pain which are the toes.
These shoes contain only three items that add cushion and support: cotton balls, instant wings, and gel inserts
The shoes contain cotton balls which are added at the bottom of the shoe as well as on the back of the shoe band and the roof of the shoe toward the front. This provides cushion on the toes as well as around the foot.
There are instant wings (one in each shoe) that goes toward the front of the shoe on the roof of the shoe. These wings are meant to give additional support so that being on the toes is less straining.
There are gel inserts on the side of the shoe which provides both cushion and support to the foot. With the placement of these gel inserts, it helps hold up the foot from the sides so that there is less contact with the toes to the bottom of the shoe, giving a more lifted feel.
The Law of Conservation of Energy states that energy cannot be created nor destroyed. When the dancer has the shoes on and is ready to dance, the dancer has potential energy and when the dancer begins to move and hop onto their toes, that energy is converted into kinetic energy. Furthermore, when the dancer’s muscles are flexed, they contain elastic potential energy which is then converted to kinetic energy once the dancer starts dancing. The dancer also has gravitational potential energy when the dancer’s on their toes. That energy will then get converted into kinetic energy when they allow their body to drop back down.
Additionally, in regards to Conservation of Momentum, momentum cannot be created nor destroyed. The dancer continues to move more quickly as the dancer moves across the floor. The velocity increases which increases the dancer’s momentum. Since the dancer’s mass stays the same, the dancer needs to increase their velocity for the momentum to increase. The dancer’s foot collides with the ground as the dancer hops onto the foot, pushes down, and lifts up their body on the dance floor.
In regard to Newton’s laws, when the dancer is in a preparation stance, the dancer has to break the state of inertia and apply force. The dancer will eventually have to push off and accelerate. In Newton’s second law, the dancer would have now pushed off onto their toes. The dancer will move their arms around which adds force that moves the dancer forward. The dancer continues to move which creates more acceleration and she travels a great distance. In Newton’s third law, as the dancer continues to move and place their foot down to push off, there is an equal amount of force that is applied. Their foot applies a force to the floor, and the floor applies an equal amount of force back. Then, as the dancer finishes dancing and is prepared to land, the dancer lands on their feet in a still position and there is also that equal force being applied. Also, when the dancer is turning, the dancer moves from one corner of the floor to the other, which is the displacement of the dancer’s distance traveled.
Since there are a lot of collisions between the dancer's foot and the ground, this prototype strives to increase the energy absorption to minimize strain, pain, and ultimately injury. Unless a dancer is doing a jump, or leap, their feet are always on the ground and constantly colliding with the floor. The constant collision can become painful when dancing for a prolonged period of time. With this design, the cushion and padding helps to increase the energy absorption level so that there is less energy used by the dancer to help eliminate pain and stress on the feet. The foot is supported and lifted within the shoe so that there is minimized contact with the foot and the floor. As Newton's third law states, for every action there is an equal and opposite reaction, and that is what is happening with the collision of the dancer's feet to the ground. If there is less impact when colliding with the ground, then there is less impact returned to the foot, thus this new pointe shoe was created to execute this concept. When wearing the shoe and going up on the toes, there is immediately more comfort since the foot is more elevated and there is padding to cushion the foot in needed areas.
To answer this question: yes! This product was tested several different times and compared to various independent variables. The table to the right demonstrates time to discomfort, or how long I could stand on my toes until I felt any pain or discomfort. I tested how well it worked by standing on my toes with the shoes for as long as I could. The first variable on the graph was the pointe shoe without any materials and I was only able to last an average time of 2:13 on my toes. As I continued to add more materials, the time continued to increase. Eventually, when I got to testing my completed prototype, I was able to last 15 minutes on my toes, which was a drastic time change compared to the original pointe shoe with no changes. The results and this data shows that this prototype is effective in what it is supposed to do. The prototype provided more comfort and support which is shown in the difference in time from the original pointe shoe to the new pointe shoe.
