Hiking insoles

Why replace the original insole?

The hiking insoles supplied with your boots are often generic. Their support and cushioning are usually limited. By choosing a more advanced insole, you benefit in several ways:

How to choose the right hiking insole

The choice of an insole depends on the type of outing you have in mind:

Some technical insoles are versatile, but others are truly designed for a specific activity. Always check compatibility with your footwear.

Sidas insoles are designed to precisely match the shape of your foot. Their 3Feet range offers three levels of arch support (Low, Mid, High), depending on your arch type. They combine breathable materials, targeted cushioning zones, and excellent durability. Their ability to absorb shocks makes them a particularly popular choice for trekking or long hikes with a backpack.

Cushioning insoles often feature gel or high-density EVA foam to protect your joints. Cushioning is especially useful on descents or rocky terrain. It helps reduce pain in the heels, knees, or back, especially when carrying a heavy load. Some insoles offer reinforced inserts in the heel area, the zone most exposed to impacts.

The right insole also means fewer blisters

Internal friction in your boots is one of the main causes of blisters while hiking. A well-fitted insole reduces these micro-movements of the foot, which over time can cause hotspots or even burns. Materials such as microfiber or memory foam help distribute pressure more evenly and provide a more stable fit. Pair them with hiking socks that are breathable and seamless to maximize the effect.

Thermal insulation: keep your feet warm

In winter conditions or at high altitude, an insulating insole is a real asset. Made from felt or thermo-reflective materials, it reduces heat loss through conduction with the ground. This can add several degrees of thermal comfort. Combined with a warm boot and merino wool hiking socks, it forms an effective barrier against the cold.

Care, replacement, and "repair"

To extend the lifespan of your hiking insoles, remove them after each outing to air them out. Clean them with lukewarm water and a little soap if needed, and let them dry naturally.

Consider a new insole as soon as you notice a loss of support or significant flattening. A worn shoe insole can create imbalance and contribute to injury risks in the medium term.

Finally, if your boots are a bit too roomy, a thicker insole or a double insole can adjust the internal volume without compromising comfort.

Orthopedic insoles: when should you consider them?

If you suffer from chronic pain, foot deformities, or specific conditions (such as hallux valgus, leg length discrepancy, etc.), custom-made orthopedic insoles may be necessary. Unlike comfort insoles, these are prescribed and made by a podiatrist after a clinical assessment.

Insoles sold on Glisshop are not a substitute for a personalized orthopedic solution. If you are unsure, consult a professional before investing in a standard insole.

Which insole for which foot type?

Arch support should match your foot shape. Generally, we distinguish:

Brands like Sidas offer models specific to each profile. Good arch support can also help correct your posture slightly and prevent excessive fatigue over long distances.

Frequently Asked Questions

Choose a breathable insole with an anti-friction top layer and good moisture-wicking properties. Memory foam or micro-perforated materials help prevent hotspots. Paired with a good pair of hiking socks, this solution effectively reduces overheating.

Opt for a trimmable insole that you can cut to fit the size of your boot (not your foot). Use the original insole as a template to trim the new one. A thicker insole can also fill up the volume and improve support without hindering your stride.

There is no universal model. The best insole is the one that matches your foot shape, your activity (hiking, trekking, trail running), and your needs (cushioning, support, insulation). Sidas insoles, for example, offer specific versions according to your arch type and provide an excellent comfort/performance balance. Try several models if needed to find your ideal fit.
