Zamberlan Replacement Thermal Footbed 47. Ideal for alpine boots and cold weather applications. Footbeds should ideally be replaced every six to twelve months depending on usage in order to continuously offer responsive cushioning and hygiene. As the footbeds are unisex they will fit both Zamberlan Men's and Women's footwear necessitating the use of EU sizes. Please see your Zamberlan boots or shoes for their EU size or refer to the size chart for the model you own. For half EU sizes please buy the next largest size and trim to fit if necessary.
