Heel pain is commonly caused by rolling over of the foot ('excess pronation'). As the foot pronates, the arch collapses and the muscles and supporting structures are forced to stretch and elongate. This puts stretch (traction)and strain on the ligaments running from the heel to the toes.
In turn, the heel bone may 'respond' by developing a bony growth right in the centre of the -the heel spur.
VASYLI products re-align the foot , reducing the stetch (traction) forces on the ligament - taking away this common cause of heel pain.
