The Winter Custom Race Merino insoles by Sidas are made to support you during winter activities. They have to be adjusted to your feet, which makes for increased stability and precision, plus, they prevent fatigue.

The top cover of the Sidas Winter Custom Race Merino insoles is made of 60 % merino wool and 40 % synthetic fibres. This makes the insoles become more durable and also helps to absorb odours.

Features:
• Hybrid merino top cover: thermoregulation and absorbs odours boots
• Narrow shape: for narrow boots
• Transflux reinforcement: foot support and rigidity
• Podiafix: precision

Please notice:
These insoles have to be individually adjusted to your feet. Thus, we recommend buying them directly in one of our stores.
