Superfeet Flex Insole Reviews

When you want to show your feet some love, Superfeet flex insoles will be a perfect addition to your footwear accessories. Superfeet insoles are known for their premium quality and comfort, helpful in alleviating stress on the back, knees, and feet.

With their latest edition of Superfeet flex insoles, they just took the insole game to a whole new level.  Superfeet Flex insoles are doctor-recommended, excellent for controlling discomforts that come with high-impact activities.

They will be your best bet if you need to power your performance on the field, track, or in the gym. They are also helpful for inserting into your shoes when wearing them for long hours to work or your casual events.

You can wear them with slim or roomy footwear without needing to cut or trim them. This is because Superfeet flex insoles are made to bend and conform to the shape of your shoes. All Superfeet Flex insoles are ventilated and wick away moisture effectively.

Superfeet Flex Insoles Features

Let us talk now about what makes these insoles stand out from the other Superfeet insoles as well as other brands in the market.

The Aerospring or Viscoelastic Foam

This will give you long-lasting comfort as it absorbs shock and flexes effectively with your sudden foot movement. It is a closed-cell foam made to endure heavy weight and the frequent compression of your feet as you run, walk, train, or play your favorite game.  

The elasticity of this foam is significant in sucking up the pressure you exert with your feet and distributing it evenly so that it does not damage your joints, lower back, knees, and feet muscles. It is a medical-grade foam that doctors recommend for protecting and alleviating discomforts associated with heavy-impact activities.

Flexible and Comfortable Cradle

As you engage in your training, sports, or leisure activities, you want to ensure you maintain a strong upright posture. You also want to minimize the risk of losing your balance and stability when moving your feet speedily. Superfeet Flex insoles have considered that and incorporated a deep and flexible heel cradle. This is significant in absorbing shock, giving you flexibility, and powering your bounce.

Biomechanical Shape

Nothing irritates like having ill-shaped insoles that do not conform to the contours of your feet. They make you uncomfortable and interfere with your movements. This is unlike Superfeet Flex insoles that contour and curve around your foot naturally to give you maximum support.

They are made with consideration to how your tendons, bones, ligaments, and muscles work to generate your foot movements. These insoles are constructed to imitate your natural foot anatomy to serve you and give you every support that an insole should.


The insoles are made to last you 12 months of heavy use. The manufacturer states that they will take you through 500 miles before showing signs of wear and tear or losing their power and comfort.

Ventilated and Moisture-Wicking Coating

With Superfeet flex, your feet will be aerated throughout to keep them fresh. This is perfect for managing odors and bacteria buildup. In addition, the coating absorbs moisture sufficiently to give you all-day dryness.

Rounded Edges

This is perfect for fitting these insoles into any type of footwear. The rounded edges are easy to manipulate so that they can bend and fit into your shoes. This is more helpful when using these insoles inside tight footwear when you do not want to cut them to the size of the shoe.


Regardless of your arch type, there is a Superfeet flex insole to suit your arch support needs. They come in three models. Low profile Superfeet insoles are 3mm thick. They are ideal for people with flat feet or a low arch.

If you have a medium arch, you will be more comfortable with the 4mm thick flex mid insoles. On the other hand, Flex high is available for you if you have a high arch.  It is 5 mm thick but with a firm base to give you all the comfort and support of a premium insole.

Color Coding

While color may not be significant since your insoles are invisible in your shoes, the color of your insoles may be helpful when purchasing your favorite pair. Superfeet Flex insoles are color-coded so that you can distinguish them. Flex low insoles have a blue heel, while flex mid has an orange heel. You will identify your high flex insoles with their green heels.

Superfeet Flexthin Comfort Insoles

These are your ideal insoles if you wear slim athletic shoes. They are padded with aerospring comfort foam from the heel to the forefoot. With a 3mm thickness, they are perfect if you have a low arch. The aerospring foam is also called viscoelastic foam since it is stretchy, excellent for accommodating your sudden feet movement.

The forefoot of these insoles is ventilated. This is good as it keeps your feet cool, fresh, and comfortable. Their dynamic shape and rounded edges help them to fit well in any type of shoes and contour with your foot structure.

Besides, they have a deep and flexible horseshoe-shaped heel cup that provides you with much-needed cushioning, stability, and upright posture alignment. You cannot miss to notice them,  as they have a unique bolt color.
