1. The medical background

2. 2 systems: 1.Passive shock absorbtion system 2.Active shock absorbtion system The human shock absorbtion system

3. Discs Tendons and ligaments Cartilage The passive shock absorbtion system

4. „Small supportive and stabilizing muscles“ The active shock absorbtion system

5. Anatomy (left ankle-joint/ rear view) Lateral upwards turn of heel bone Natural heel strike on lateral part of heel bone(Supination) The natural roll through

6. Loading in the outer heel area during heel strike (Supination). Roll-through begins. Foot turns from outer to inner side (Pronation) and midfoot twists inwards joint by joint (Torsion) Roll-through from the forefoot to the big toe.

7. How Joya can be supportive with foot pain

8.  Fallen arch  Flat foot  Skew foot Joyas' supportive, therapeutic effect: Exercise muscles around foot joints Natural roll-through via outside of foot Cause: Weak foot muscles (e.g. due to lack of exercise, rarely walking barefoot) Flat shoes without footbed

9.  Splayfoot Joyas' supportive, therapeutic effect: Exercise muscles around foot joints Soft PU takes pressure off forefoot Natural roll-through via outside of foot Cause: Wearing unsuitable footwear, especially high heels With splayed feet there is too much pressure on the second to fourth metatarsal heads, creating fallen transverse arches.

10.  Metatarsalgia Cause: Mechanical overload of forefoot (especially high heels) Fashionable,tight shoes Joyas' supportive, therapeutic effect: Soft PU takes pressure off forefoot Natural roll-through via outside of foot

11. Joyas' supportive, therapeutic effect: Soft PU takes pressure off forefoot Natural roll-through via outside of foot  Hallux Valgus (Bunions)  Hallux rigidus (+ stiff big toe joint) Cause: Mechanical overload of forefoot (especially high heels) Fashionable,tight shoes

12.  Plantar fasciitis  Heel spur Joyas' supportive, therapeutic effect: Exercise muscles around foot joints Natural roll- through (Relief of plantar fascia) Stretch of calf muculature (Sink in movement in soft PU) Cause: Mechanical overload (mainly due to fallen arches or high arches..) Micro-injuries

13. How Joya can be supportive with back pain, arthrosis and diabetes

14. Joyas' supportive, therapeutic effect: Pelvic movement as the foot sinks into the soft polyurethane sole Load equally distributed when standing Soft sole cushion impacts Cause: Mechanical stress and overload Sedentary lifestyle (Shortens the hip flexor and causes a forward rotation of pelvis) Back problems

15. Joyas' supportive, therapeutic effect: Training of small stabilizing muscles around ankle- and hip joint Stabilization of leg- axis Cushioning effect of soft PU Cause: Abrasion of cartilage due to mechanical stress and overload Joint- hip – knee arthrosis

16. Diabetes is a metabolic disease. It may result in:  Nerve damage (neuropathy)  Diabetic foot Joyas' supportive, therapeutic effect: Soft sole relieves pressure on damaged structures Sensorimotor exercise (proprioception) Comfort last (stops rubbing) Diabetes
