3 Arches, 3 Structures, 3 Rotations

While walking or running, the impact forces on the feet during each step can be up to nine times a person’s body weight. The three arches in a person’s foot consistently absorb the force generated by body weight and gravity while providing driving force and balance to the body. Without proper arch position, your feet will be overwhelmed by constant stress and joint damage. This will lead to foot pain, knee pain and more serious conditions.

3 Arches

"Of all the bones in the foot, the Talus, Cuboid and Middle Cuneiform are structurally very important. If one or more of these three bones is out of alignment, the structural integrity of the arch it supports, and in turn the strength and stability of the entire foot becomes compromised."
- ​Thomas Michaud, 1993.

3 Structures

Foot types are generally classified into one of three categories:
​flatfoot, neutral, and high arch.
Picture

Flatfeet

Structural or Functional
High stress on the heel
In-toeing or very out-toeing
X-shape legs
​High risk of hip pain
Picture

Neutral

Great feet!
Please take care of them
Picture

High arch

Mostly starts at age 3 
High stress on lateral ankle 
Out-toeing
O-shape legs
High risk of plantar pain

3 Rotations

When your foot touches the ground, it will slightly rotate 3 times in order to absorb shock, maintain balance and provide driving force. This only takes about 0.7 seconds.
