What footwear is best for accommodating an Orthosis?
It may be necessary to change your chosen style of footwear if your orthosis is to be effective. Shoes or boots should have a strong, wide, supportive base. Any shoes with a heel higher than three centimetres are generally unsuitable for use, as are most types of slip-on and court shoes, as they will either end up too tight or slip off when walking. Generally, trainers or other shoes with a fastening (laces or Velcro) are the best for accommodating orthoses.
Removing the original inlay from inside your shoes will create extra space for your orthosis.
