The factory-supplied insoles that come with ski boots are usually better than most factory insoles, but they are designed for a generic foot shape, not your unique foot.

SOLE Custom Footbeds feature an orthopedic base layer that molds to your unique foot without losing its supportive shape. This custom support cradles and stabilizes your entire foot, lifting your arch into its optimal position. This increases feel and corrects alignment, allowing your body to perform at peak potential. This means improved balance and weight transfer, making your skis feel more responsive, and your turns more efficient. When your body is performing at peak efficiency you can ski better, for longer.
