CURREX works together with the foot and adapts to its natural roll-through movement. In the loading phase – that is, when the body’s full weight is borne by the CURREX – the dynamic arch cradle (DAC) flattens and enables full muscular activity. Only in the case of severe fatigue and/or movements such as overpronation does the arch cradle protect against damaging peaks in loading. In the toe-off phase, the DAC springs back and transfers the saved energy myofascially (myo (Gr.) = muscle; fascia (Lat.) = connective tissue) to the plantar tendon, which increases strength in the toe-off phase.
