Criteria Used for Evaluation

Support

The best insoles for flat feet will lift the arch enough to ensure better support when they are worn correctly.

Here we looked at the most critical factor in choosing running inserts for flat feet: arch support. It’s important to have the right support for your specific situation in order to effectively treat and reduce the stress typically put on your feet during your runs and avoid placing stress on the center of the foot’s arch when making contact with the ground.

Height is also important because if it is the arch is too high or too low the insole will be ineffective and create an uncomfortable situation. So when buying flat feet running shoes online, make sure they go well with your inserts. A lot of the inserts on our list can be trimmed down, so if you need to make them fit your shoes these may be a good option.

All in all, the flat foot insoles on our list of reviews are all made for runners and athletes who have flat feet--but that doesn't mean that they are exactly the same. In fact, they each offer various different levels of support--so there is definitely something out there for all types of runners with flat feet or fallen arches. Bear in mind that if it's good for high-intensity foot strike like during runs, it's good for everyday walking. The vice versa might not be the case. So be sure to investigate both insoles for flat feet running and walking depending on your needs.

Size

The fit of the insoles is critical as it can make them highly uncomfortable in the shoe when they are worn.

Here we focused on how the insoles fit into your favorite pair of running shoes, if they have gaps along the sides, are too short or too long for the shoes, or if they are too wide–all of these factors can affect the intended function of the insoles as well as make them highly uncomfortable.

That being said, there are many insoles out there that can be trimmed as needed to get a better fit–these areas, however, are usually on the forefoot of the insole. Luckily, the heel is easily adjustable–so if the rest fits you shouldn’t have any problems here. Lastly, we made sure none of our options were to narrow since this can cause irritation and balance issues.

In the end, the right fit is one of the most important factors to consider. After all, if the inserts you get don't fit your shoes and your needs you will end up wasting money and ending up right back where you started. Make sure to keep your needs and preferences at the forefront if you want to be sure you are getting the perfect insoles for you.

Durability

Some insoles provide shock absorption, enhanced breathable, removable top covers, and the ability to be trimmed down.

When looking for the best shoe inserts for flat feet, durability is key. No one wants a product that is going to break down us and needs to be replaced in the recent future–and this is especially important when it comes to insoles we plan on using during our runs. We want a product that holds up over time and that means insoles for flat feet with a more rigid in design than those made for casual wear.

Some insoles provide shock absorption, enhanced breathable, removable top covers, and the ability to be trimmed down. These are all important because it’s important to use a product that will hold up to the demands running puts on them over time without having to replace them on a consistent basis.

All in all, we all want to invest in a pair of insoles that will last you the long haul. However, it is important to note that if we want our insoles to last we need to make sure we take care of them properly as well. Make sure you care for the insoles appropriately so you can help extend their life over the long run--if you take care of them they will take care of you!

Use

People who stand or walk all day will get benefits from shoe insoles and can see resutls almost instantly.

An insole is located inside the shoe, directly under your foot. Many insoles can be removed from shoes and replaced with a specialty insole or orthotic. Insoles are meant to provide the wearer comfort, may have moisture-wicking/odor resistant properties and/or provide arch support.

Insoles help individuals correct their foot function. Insoles help realign the foot and ankle to a neutral position, which can help alleviate underlying issues in joints, muscles, tendons, and others. In addition, shoe insoles can help distribute weight more evenly, absorb the shock of impact, and take the pressure off sore spots such as bunions, the ball of the foot, etc.

Shoe insoles enhance the comfort of your feet, too. Individual generally purchase insoles for three main reasons: absorbing shock and reducing joint pain, foot odor control, and all-day comfort. If you are working long hours on hard surfaces, the best insole for you is one that is a gel or air foam.

For flat feet, the foot could have imbalances which can lead to an excessive inward rolling of the foot, also known as over-pronation. Abnormal foot motion such as overpronation can happen if the foot has an imbalance. Over-pronation can result in injuries in the knees, hips or even back.

Balance is especially important, as the force of impact experienced while running with imbalances can lead to serious injury, discomfort and incorrect running form. In conjunction with the proper footwear, insoles can help improve these imbalances as well as alleviate pain and discomfort.

People who walk all day will get benefits from shoe insoles. For overweight individuals, a shoe insole can greatly reduce the added pressure the extra weight can cause. Make sure to consider your weight before making your purchase and really take the time to read through reviews to see how they really hold up.

Comfort

It is important to confirm that any insole you purchase fits your foot and arch appropriately for optimal comfort.

It is necessary to choose an insole that is neither too rigid, nor too flexible. because an insole which is too firm won't be able to absorb the shock from any regular physical activity. When energy applies force to this type of device, the design or material of the insole doesn't provide enough compression, resulting in most of the impact stress transmitting back into the joints of your body.

This can often lead to knee, back and ankle discomfort. While at first, an extra cushy insole might feel really good, in the insole lack support and cannot safeguard against the painful issues associated with flat feet. These types of insoles are often made from a compressed foam material. It is always apparent in the first few uses that the support provided is not enough.

Most inserts for flat feet sold on the market are in “approximate sizing.” Because of that reason, this leads to an inadequate fit for many users. Some individuals may be “in-between” sizes for the vast majority of insoles on the market, making them believe that an over the counter insole may not be effective for them.

In order to get the best fit and effective insoles, it is important to confirm that any insole you purchase fits your foot and arch appropriately, not depend on the manufacturers’ suggested sizing too much. Regardless of the inserts you ultimately choose, it is necessary to break into these types of devices over a prolonged period of time.

Your foot cannot be accustomed to the level of support a new insole provides, your feet need extra time to adjust to the correct biomechanical (walking) position. Lastly, you should often read reviews or information about inserts for flat feet, to see what others are reporting as specific qualities which may help with quick relief.
