NESKRID’s unique certified custom orthopaedic shoes in category A meet the European legal standards of EN ISO 20347:2012 or EN ISO 20345:2011. NESKRID manufactures a custom orthopaedic (safety) shoe based on the shoe last supplied by the NESKRID dealer. NESKRID uses the supplied last to design a custom upper of the NESKRID model chosen by the customer. The material chosen for the sole depends on the conditions for usage and may be made from polyurethane (PU), nitrile rubber (NI) or a combination of both. This results in the optimal sole selection or structure. Because NESKRID works exclusively with tested and certified materials, the certified shoes meet all the requirements the user might have for their orthopaedic shoes, all the while safeguarding durability.
