Quick Look: Our Top Picks

The role of an insole

Basically, an insole is the removable layer inside a shoe that serves as a cushion and adds extra comfort for our feet. It can come in many shapes and sizes, depending on the shoe style. Insoles are also designed to fit different foot types, which is why you should know your foot’s form and know what type of insole to use.

Why do you need insoles?

As a runner, you are always on your feet, and you put a lot of stress on your joints, especially when you are training. If you are not careful, and if you are not equipped with the right protective gear, one wrong move can cause pain and injury to your ankles, knees, and hips.

Wearing the right kind of shoes can help a lot, but it would be better if they also came with the right insole. Insoles can provide shock absorption and can help distribute the stress that you bear along your foot.

In addition, there are also some insoles which can provide more support for your feet, especially in cases of overpronation. Insoles can also help alleviate pain caused by plantar fasciitis, which is the tearing of tissues and ligaments at the bottom of the foot. A supportive insole is usually prescribed by specialists and therapists because it can aid in the healing process.

Different types of insoles

There are three basic types of insoles that you can choose from: comfort insoles, support insoles, and custom orthotics.

  • Comfort insoles are usually used by those who need relief from prolonged standing, walking, or running. They are usually made from a soft foam or gel, which helps with the shock absorption and cushioning.
  • Support insoles were designed to address issues such as overpronation, splayed feet, plantar fasciitis, and other related ailments. They are usually made from a harder foam to help add support and stability.
  • Custom orthotics are specifically designed for chronic foot problems. Therapists usually recommend the use of a custom insole if comfort insoles or support insoles do not work.

Use of insoles to treat flat feet

Supportive insoles can help stabilize your arch and heel area as a treatment for flat feet. However, you do not really fix flat feet because it is not a disorder; flat feet can either be inherited or can develop on their own. Whatever the case may be, having flat feet can have some disadvantages, especially for runners. However, these disadvantages can be turned into opportunities, and it is up to you to do that.

Things to consider when choosing the best insoles for flat feet

When choosing the best insoles, you should come up with a list of things that you can look for. Does it provide sufficient arch support? Will it provide the right support to treat and reduce the stress on your feet? The recommendation is that the best insole should be able to lift the arch enough to provide support and reduce stress on the center of your foot’s arch.

If you run a lot, it is also important to consider how insoles can fit into your favorite running shoes. The insoles should be a perfect fit as much as possible, because they can also play a vital role in your road to achieving your fitness goals.

Of course, everyone wants a product which is durable enough so that it can be used for a long time. Since you will be using these insoles mainly for sports activities, you should go for those which are made from high-quality materials and will not easily wear out.

It would be best if you can find an insole which has shock absorption, removable top covers, and are made from breathable materials for comfort.
