We know from several studies that an asymmetry exists in foot pressure on an erg and on the water, whether that be sculling or sweeping.
This asymmetry in foot pressure may affect boat speed and cause a sheering force at the hips and spine. This could contribute to back pain or back injuries.
Symmetrical ankles may play a part in limiting these asymmetrical forces. Asymmetrical ankles may play a part in contributing to these asymmetrical forces.
One study found that high density textured insoles may help rowers balance out foot pressure, increase stroke length, and apply greater force to the footplate. May be worth looking into...
Are your ankles symmetrical?
