Some people have more "gravity" than others when standing. The issue is called variable weights.
The distinguised and awarded engineering
in barefoot goes well-beyond the simple up-and-down mechanics found in other mats.
Here is a brief review.
The Patented Mechanical Workings
Cushion (dome compression) begins early at 4 pounds at center or 5 psi. Compliance is matched with Support from tensile.
Under greater force, flexible legs give-way to another level of support after further compliance of the structure and material.
Hexagons - one of the strongest structures in nature - is the foundation of Barefoot. The structure's ability to flex without collapsing adds another dimension of support.
A "direct strike" is the moment when 100% of a person's weight is on one single heel. Deflecting kinetic energy is an important part of an effective mat. From the beginning Barefoot was designed to deflect kinetic energy by channeling the energy away from the strike-point.
