FootCore MAX Clinical Studies

        The FootCore MAX exercise is more effective than the $4.7 billion dollars spent on orthotics each year.

        Over 100 Independent academic studies have shown remarkable results for people that do the FootCore MAX exercise:

        •  Arch Height increases up to 20% (30 million Americans with flat feet)
        • Performance during a balancing-tests improves significantly
        • Increases core stability in athletic function
        • Increases ankle stability
        • Mitigates lower back pain in tested indications
        • Best tested therapy for Plantar Fasciitis

        In 150 published studies, there is clear evidence that activating intrinsic foot muscles is one of the best methods of therapy for these indications:
