Orthopaedists very often recommend moderate barefoot walking to strengthen the foot muscles in these cases. Sock shoes provide optimum protection against injuries. The special feature of sock shoes is that the feet generally have a much greater range of movement and much less support than in normal footwear. Wearing sock shoes therefore has a special training effect on the foot muscles and can counteract the development of fallen arches. In individual cases, however, it is advisable to ask an orthopaedic specialist for advice on the long-term use of sock shoes.
