The orthotic inserts that we supply are described as semi rigid, whilst this means they are not as supportive and controlling as the hard types, they are a lot more comfortable to wear. They do over 95% of the job of a rigid corrective device for the vast majority of people. If we feel that the products that we supply are not going to resolve any biomechanical issues then we will refer you to a supplier of a more suitable product. All our orthotic products come backed with a 60 day money back guarantee so you can be sure that we believe they are the best products available.
