The little-known way rowers are losing force and energy…

In rowing, just as the leg drive is initiated, the feet flatten out, the forward arch (behind the ball of the foot) collides with the inside of the shoe, and force is transferred through the shoe…

It is these collision forces that cause energy to be lost in the process. 

The flexible arch piece in the 2620’s, fitted forward in the arch, behind the ball of the foot, eliminates these collision forces and transfers force over a larger area.

After completion of the leg drive and into the recovery phase, the forward arch of the foot is still in contact with the flexible arch piece of the 2620, and the process repeats.

This helps keep the feet engaged with the rest of the kinetic chain and prepare for the next leg drive. Reducing the number of collision forces at the forefoot results in lost energy at the point of impact.

The increased efficiency produced from a flexible arch piece (similar to a car’s suspension) also reduces unused force from being returned to the point of origin (hips, lower back, knees)
