An athlete’s worst enemy is the “absorption” concept which remains a sales pitch for different companies of the sports industry.
Indeed, absorption material does reduce shock waves but it does not absorb the forces of the movements.
Absorption material distributes the forces and the number of vibrations improving comfort, although vibrations are essential for the mineralization of the bone.
Therefore there will always be standard shock norms to be taken into account
– high absorption , less shock waves = causes demineralization of the bone
– excess shock waves, less absorption = tendonitis, fatigue or bone fractures …
In addition, absorption inevitably leads to instability increasing static disorders, especially if the foot is not properly positioned in the natural axis.
A shoe must provide the foot with good stability allowing it to play its natural role as a shock absorber, stabilizer and propulser.
