Foot insoles, lifts, and pads are used to absorb shock, decrease pain, and prevent damage. Excess weight, athletics, repetitive activities, and standing for long periods can inflict pain and limit activity. These activities affect your knees, hips, and lower back, as well as your feet. Sufficient cushioning is rarely found in modern foot ware. Most sport shoes do not offer protection and aren't suitable for work or business use. Studies show that using insoles, cushions, lifts, or pads would help relieve pain and prevent further damage.
