Foot is the basic foundation of human body. Its a complex but unfortunately most ignored structure. If the structure of Foot is abnormal (Studies shows it's as high as 50% in affluent classes), it can lead to problems at various levels of the body starting from Knees, Hip, Spine, neck etc. In cases of Knee replacements one of the Major reasons observed is FOOT MISALIGNMENT. it may not affect you immediately but is really bad and non reversible in long terms. There are good chances of getting the alignment corrected if this can be early diagnosed and treated. Its possible even without medicine and surgery.
