Sidas 3-Feet ECO Warm Insoles

Designed to fit inside nordic ski boots, these thermal insoles not only add insulation under your foot but they come in 3 different arch heights: low, medium and high arch support. The EVA shell provides stability and foot support, holding your heel securely back in the boot so it fits the way it is supposed to. The arch support is significant - just standing on the insole alone you can feel the support under the arch. We highly recommend these as most nordic ski boots have very basic insoles.

To wash your insoles use a soft brush and soap. Do not dry on a radiator.
