Effect of medial arch-heel support in inserts on reducing ankle eversion: a biomechanics study. Journal of Orthopaedic Surgery and Research, 3, 7
Wearing Dr Kong health shoes can reduce pressure around the big toe and increase total contact area at heel which spread pressure evenly along foot bottom. By significantly reducing the pressure at metatarsus, it increases the balance and symmetry at walk.
In comparing the health shoes and footcare shoes provided by Dr Kong and those children shoes obtained from the market, the static and dynamic analysis processes show that Dr Kong insole products can help foot joints to restore normal eversion range.
When comparing the testing report for Dr Kong 5-elements chirobag with two other chirobags from the market, the result shows that the cervical vertebra of school children has less inclination. Their bodies lean forward in a smaller degree and their heads have less lateral displacement which reduces pressure at neck and shoulder.
