You know all about finding properly fitting ski boots? Maybe because you have read our ski boot fitting guide? That’s great! But did you know that you can improve your comfort (and your performance!) even more by “pimping” your ski boots? Upgrading your boots with functional insoles can make a major difference.

How is that possible? What types of insoles are there, and which ones are perfect for your needs? Together with the winter sports experts at Sidas, we have compiled a comprehensive overview of functional insoles for your ski boots.

Why should I buy functional insoles for my ski boots?

The answer to this question is pretty simple: Because every foot is different. Whether you buy running shoes, hiking boots or ski boots – the standard insoles that come with the products might not necessarily fit your individual foot shape.

Functional insoles (also called footbeds, inserts or orthotics) improve pressure transfer from your foot to the boot, thus increasing your comfort – and, ultimately, your performance on the slopes.

Who needs functional insoles?

Basically, all types of skiers benefit from functional insoles:

  • For 85 per cent of skiers, the foot elongates as you flex, causing your toes to crash into the front of the boot. A functional insole can stabilise and support your foot to avoid this.
  • For skiers with inflexible feet, insoles can help to spread the body weight more evenly along the foot, resulting in improved control and reduced fatigue.
  • Even if your feet offer enough stability and flexibility, you can still benefit from increased comfort, warmth and performance with functional insoles.

What are the benefits of functional insoles?

Good-quality insoles like those by Sidas offer a number of advantages. They …

  • … provide arch support and foot cushioning.
  • … offer stability and comfort.
  • … promote good body alignment.
  • … absorb shock during skiing.
  • … reduce pressure points and consequently also joint and muscle pain.
  • … prevent overheating and fatigue.
  • … help to reduce odour thanks to antibacterial materials, merino wool and sanitised treatments.
  • … provide thermal insulation and warmth.

The conclusion:

Ski boot insoles offer both short-term and long-term advantages. In the short term, they provide more comfort, better support and increased protection, resulting in less fatigue. In the long term, there is less strain on your joints.

How do I find the right insoles?

Choosing the right type of insoles depends on several factors:

  • your arch shape (low, medium, high)
  • the degree of warmth you’re looking for
  • your preferred type of activity (skiing, snowboarding, ski touring, …)
  • the intensity of your activity

Depending on your individual needs, Sidas offers different types of insoles, ranging from heated to thermo-moulded insoles for women and men.
