Slimflex Orthotic footbeds are widely used by NHS practitioners and have perfect applications in everyday use. They are an 'off the shelf' solution so can be used with no prescription. For use in winter sports footwear the Slimflex plastic is perfect for anyone with special emphasis for people (which is over 75% of people) who over supinate or over pronate. These are very similar to Superfeet but for a fraction of the cost!
