How to choose your insoles


The foot is no less than 28 bones, 16 joints, 107 ligaments, and 20 muscles! So many elements, multiplied by two, mean that you need to take care of your two feet that support the weight of your body. 

The role of the foot

The foot is your only point of contact between your body and the ground. It plays a critical role in the biomechanical stability of the human body. Every day, your feet support you and the weight of your body. They allow you to move and stay balanced.

What are insoles for?

Many people are not comfortable in their shoes and blame the model or brand, whereas the shoes are made with a precise shape in order to ensure constancy in manufacture. You can feel uncomfortable in your shoes because the shape is not adapted to your body type, for instance. But you can limit this problem by putting suitable insoles in your shoes.

Depending on the volume of your shoes, you can replace or add insoles. You can add insoles to add height and fill the shoes to the right volume, or you can replace the insoles by adding a more comfortable pair that is better suited to your body and your needs.

What are foam insoles?

The most commonly used material in insoles is open-cell PU (polyurethane) foam. It provides good absorption of perspiration and prevents the stagnation of moisture in contact with the foot, thus preventing the proliferation of bacteria. This way, the foam enhances air circulation and regulates moisture, which contributes to better foot ventilation. This lightweight and durable material ages well and will provide better shock absorption and better foot stability. This type of sole is perfect for people who are standing all day, since it relieves the pressure exerted on points of contact with the ground.

You can add insoles with a fabric covering (polyester, cotton, etc.) for perspiration wicking, or a covering in leather, a material well-known for absorbing moisture and perfect for daily use in town, such as the Aptonia Comfort 100 leather (3 mm thick) and the Aptonia Comfort 300 leather (5 mm thick).

What are gel insoles?

Insoles made of gel guarantee very good cushioning for your feet in the front and back, as well as good shock absorption. This type of sole can be cut for a perfect fit; this way, they can adapt to all shoes.

Perfect for all sports, gel insoles limit vibrations to provide true comfort, even during intense exercise. What's more, they are most often perforated for better ventilation, and they can have an anti bacterial covering.

Choose your insoles based on your sport

There are insoles adapted to your sport and your needs:

If you practise a linear sport, such as hiking, running, power walking, or cycling, we recommend insoles from the Aptonia SHOCK range. They are 5mm thick, which provides good cushioning, and have inserts made of Poron® (a high-performance material for better shock absorption and a long lifespan on cushioning) or gel, which provide more comfort when the foot strikes the ground.

If you practise a pivot sport, such as trail running, tennis, football, basketball, or rugby, we recommend the Aptonia Stability 500 soles, which will provide stability during your sport.

Insoles for keeping your feet warm:

There are insoles that allow you to keep your feet warm in winter. The underside is made of a felt material, a true insulator in contact with the ground in the insole. The top, in contact with your skin, is made of synthetic wool, which is a true heat source that provides real comfort. We recommend the Aptonia Warm insoles, which provide 5 extra degrees according to our climate test.

How to cut your insoles so that they are your size

Remove the insole that is already in your shoe, and get your new insole. Put the two insoles on top of one another, and follow the pattern of the sole to cut your new sole.
