Frequently Asked Questions
Below are some questions and answers which we often deal with. If you have a question that is not covered here, please contact us.
What are insoles?
An insole is an in-shoe device which alters the characteristics and biomechanics of the foot and ankle area. Biomechanics are concerned with mechanical laws and how they affect the living body, especially the musculoskeletal system. They are removable devices, often made from eva and plastic, that are designed to fit inside a shoe to provide additional support for your feet. As well as offering shock absorption, an insole can help distribute the weight of your body more effectively across the foot and can be made bespoke to cover a range of biomechanical conditions.
How do I know I need insoles?
If you have symptoms in your feet, ankles, hips or your lower back that are intermittent or were not there to start with in early life, and have started to cause you pain over a period of time, orthotic insoles could be an excellent option. If you have already tried rest, icing, compression and elevation and your feet have not recovered, a biomechanical assessment might be needed to consider the possibility of insoles. They are a non-invasive approach to treatment and in many cases and are a great option for symptoms that are not severe enough to warrant surgical intervention. Alternatively, they can be considered as an option prior to surgery.
What are insoles made of?
Insoles are made from varying densities of a plastic called ethylene vinyl acetate (EVA) which is a plastic that can be reinforced if necessary. The density changes depending on the amount of cushioning and support required, and can be split throughout any one insole. Higher density EVA will often be used towards the back of the foot, where more support is generally required, and lower density EVA to the forefoot where more cushioning is needed. Other insoles such as custom made orthotics are made from polypropylene, carbon fibre which are suited to more supportive orthoses, however these materials cannot be manipulated once it has been milled out. Please contact your local NHS Podiatry clinic or private Podiatrist if you require custom made orthoses.
How long will my insoles last?
You should look to replace your insoles when they begin to show signs of wear. Purchasing a replacement pair every 4-6 months is recommended.
