Why running insoles make a difference
Running puts your feet under repeated stress: impact with the ground, alternating pressure, friction, pronation or supination, muscle fatigue. Without proper support, this stress can cause pain, blisters, poor posture, imbalances and even injuries. Insoles designed for running cushion shocks, support the arch of the foot, stabilise the foot and optimise posture — for safer, more comfortable and more efficient strides, even over long distances.
The advantages of Sidas insoles for running
- Cushioning & shock absorption — Several models (such as the ‘Protect’ range) incorporate gel pads or specific foams in the heel and forefoot to soften the impact with the ground and limit the vibrations transmitted to the joints.
- Stability, stride control & arch support — Sidas anatomical insoles provide support tailored to the shape of the foot, which helps control pronation/supination, improves stride roll and reduces the risk of imbalance.
- Dynamism and optimised propulsion — Some insoles (the ‘Sense’ or ‘Run 3D’ ranges) are thinner and more dynamic, allowing for better foot-ground contact and promoting a more responsive and fluid stride.
-
Long-lasting comfort and injury prevention — For long runs, frequent training or intensive training (as in your case), Sidas running insoles reduce fatigue, limit pressure points, prevent blisters and protect joints.
Who are these insoles for?
- Regular or intensive runners who do long runs, interval training and races — like you.
- Those looking for comfort + efficiency + protection: trail running, road running, marathon/half marathon training, frequent training.
- Those with specific issues: specific arch type (flat feet, high arches), pronation/supination, history of injuries, joint pain.
- For those who want to improve their stride — better posture, smoother transition, optimised rebound.
- For demanding runners who want to extend the life of their shoes and maximise comfort over the long term.
Expert advice & best practices
-
Choose the insole according to your foot type — flat feet, neutral or high arches: Sidas offers models designed to provide optimal support and alignment.
- Do not keep the original insole + new insole — remove the original insole before inserting the Sidas insole to avoid excessive thickness, discomfort or changes in drop.
- Test gradually — especially if it's your first time: start with 1–2 runs to allow your feet to adapt.
- Combine insoles + good shoes + suitable socks — to maximise comfort, cushioning, support and breathability.
- Take care of them — insoles can be washed with a brush and mild soap; do not dry them on a radiator to preserve their cushioning and shape.
FAQ (frequently asked questions)
Why do I feel less tired at the end of a run with suitable insoles?
Because the cushioning and support reduce stress on the joints and muscle chain — impact is absorbed, stride is more stable, pressure is better distributed.
Are all insoles suitable for all runners?
No — it is important to choose an insole based on the shape of your foot and how you use it. A ‘Protect’ insole for a heavy, pronating or injured runner; a ‘Sense’ insole for a light runner who is used to feeling the ground and looking for performance.
Do insoles change the drop or feel of the shoe?
Perhaps slightly (max. +2mm). This is why you should remove the original insole before inserting the Sidas insole. Adjust the size carefully, sometimes testing it over several sessions to check the comfort.
When should you replace your running insoles?
When the cushioning weakens, when they become deformed, lose their support, or after a certain number of kilometres — as with shoes: monitor wear and tear, loss of comfort, or recurring pain.
