The technology and the corresponding physiological idea be- hind the Joya shoe is rooted in the longstanding experience of the swiss family Müller. The knowledge is based on the studies and experiences with previous functional footwear. In addition to that the Joya Academy promotes an ongoing dialogue with the medical community (Physiotherapists, doctors, podiatrists..)
in order to improve and fine tune the technology. Therefore the Joya concept is based on scientific results of universities (Uni- versity Jena, ETH Zürich..) or medical institutions (AGR) as well as empiric science and the feedback of customers and the medical community.
Prof. Dr. Med. habit. Christoph Anders from the University of Jena conducted a study of Joya and the following is a statement after the study.
“When using the „Emotion“ model, the back is relieved because there is a measurable reduction in the average muscle amplitude values for the main stabilization muscle, M. multifidus, as compared to conventional shoes.When using the “Motion“ model, the back is activated and thus trained even more strong- ly in the sense of an unconsciously induced training (measurable increase in the average muscle amplitude values for the main stabilisation muscle, M. multifidus).
Moreover, the foot is also relieved because:
The softness (Emotion) or the forward displacement of the step zone (Motion) can have a positive effect, especially in patients with heel problems.
The Motion shoe causes a significant increase in the co-contraction of the lateral and medial compartment of the leg, i.e. the active support of the foot arch. In particular, this occurs in the phase of the initial heel contact.”
The award winning shoes at Joya are MOTION – for Active walking and standing The Joya Motion line promotes an increased late- ral-medial balance movement due to the height and shape of the sole. The curved rocker bottom facilitates the roll off which may be especially beneficial for people with arthrosis or hallux rigidus. Developed to mimic active walking and standing in deep sand.
And the EMOTION ( as discussed above) which is for Stress-free walking and standing
The Joya Emotion line generates a more stable way of walking due to the flatter sole whilst providing passive cushioning and reset forces .The WAVE technology can especially be combi- ned with orthopedic insoles. Developed to mimic joyful walking in firmer sand along the waterline.
