Hello, shoe students. If you’ve been following along with the shoe encyclopedia, you have learned a great deal and come a long way. Nevertheless, the shoe terms are aplenty in the shoe encyclopedia. So sit back, relax and read up on four more interesting shoe related words. The last lesson from the shoe encyclopedia was about the throat of the shoe, the shoetree , TS2 and Cambrelle. This time around, look forward to learning about the rearfoot, the Visible Air-Sole Unit, being biomechanically efficient and the graphite rollbar.
The rearfoot is the area behind the arch. Think about cars for just a moment to understand what the rearfoot is. In cars, the shocks absorb some of the force of impact and make that gentler on the car and riders. For a foot, the same holds true with the rearfoot. The rearfoot is there to absorb much of the impact each time the foot lands on the ground.
Existing in some New Balance shoes, the graphite rollbar is designed to stop the rearfoot from moving. To create this design, a piece of graphite is molded into the desired shape and then positioned properly in the midsole of the shoe. The purpose of installing the graphite rollbar in shoes is to create better stability in the rearfoot. This is why it must stop the rearfoot from moving.
Visible Air-Sole Unit
This is a unit inside of a Nike shoe that is visible from the side or the inside. The clear, see-through design allows consumers to see this pocket of air. The Air Sole was designed with comfort in mind. Wearers of this shoe may feel as though they are “walking on air.” In fact, they are, in a sense.
A person who is naturally biomechanically efficient has a gait cycle that is neutral. This means that person’s feet do not need extra stability support in their shoes. The reason is because the feet already are naturally designed with an even dispersion, creating natural stability. For those not biomechanically efficient, there are a wide variety of shoes that offer stability and comfort through design.
