People who experience foot pain and tired feet from standing or walking on hard surfaces for extended periods may find relief from shock-absorbing insoles designed for comfort.These can be flat or shaped and feature gel or foam in their construction. Insole choices include full length, ¾ length or arch or heel inserts.Tired, achy feet may also be the result of insufficient foot support inside a shoe. If a “comfort” insole does not provide relief, or even aggravates the problem, it is an indication that the foot wants firmer support, not more cushioning. Try a “support” style insole instead.
