Sub-4 is a podiatry/biomechanics based business that is committed to supporting  practitioners in the development of biomechanics in their clinics.

Whatever your requirements, whatever your level of expertise we can help!

Our key areas of support are:-

  • Orthoses Manufacturing & prescription hotline

Over the last 8 years we have developed a network of practitioners who we work closely with all over the UK. Some practitioners use us for supply of just a few pairs of orthoses per year, others will use us just for training and some will invest heavily in full gait lab set-up and now prescribe many pairs of orthoses per month – We tailor make our relationship to your individual requirements!
