As we have molded our landscape to form cities with well-laid out sidewalks and roads and construct buildings with tile and marble floors, we have increased the amount of time we spend walking on unnaturally hard surfaces and reduced the amount of time spent on natural land like grass, sand, and soil. These artificial surfaces do not offer any of the cushioning and shock absorbing properties of the natural landscape. This has resulted in an estimated 50% to 60% of the population experiencing foot, ankle, and lower joint pain in some form or another.
Function of Athletic Insoles
The shock and impact absorbing properties
of insoles work to combat this problem. They are designed to mold to your foot, offering more support and more cushioning. One could argue that shoes already come with enough padding, and this is often true when they are new. After walking in them for six months to a year, this padding gets compacted and loses much of its ability to effectively absorb impacts. Inserting a set of insoles into a pair of shoes is considerably cheaper than buying a new pair when the shoe's padding loses its shock absorbing properties.
