The Edea Anatomic Impact Insoles are made from EVA and pre-formed specifically for Edea skating boots with extra hold in its heel pocket and support from the raised arch. Additionally, a heel insert of Poron that stretches across the arch of the insole absorbs shock for reduced strain on the skater’s body and reduces ice chatter for a smoother glide. The Anatomic Impact Insoles are water-resistant, insulating, hypoallergenic and non-toxic. Ventilation for proper airflow is ensured by the perforations in the insole.
