OK, so you’ve got a foot condition that requires sport insoles, usually pronation (feet rolling inwards) plantar fasciitis maybe even heel pain, your friendly chiropodist, podiatrist or foot health practitioner have prescribed you a pair of sport insoles, great. But how do you fit them?
Firstly you need to look in your trainers or shoes and remove the standard insole. Take care as some manufacturers can glue in the insole so removing it may be difficult. If they are glued in then removing them may result in damage to the trainer. If this is the case or your trainers are old and worn then it maybe better to invest in a new pair as fitting a sport insole or orthotics may defeat the purpose. Fortunately most standard insoles can be removed.
Most replacement insoles work on a size range i.e. 7-9 medium 10-13 large and will need to be cut down to size. DON’T do this yet! Even if the insoles have a trimming guide on the underside it is best to trim down a little at a time and keep trying the insole back in the trainer to get a correct fit. You can always take more off but it’s very difficult to add it back on! It is best to trim the front of the insole first, you may need to trim the width but this isn’t usually necessary.
You should never trim the arch support or instep.
When you have your new insoles fitted you can put your trainers back on. Initially this will feel quite strange and you may need to wear them in for short periods at first to get used to the feeling. Not tying up your laces as tight as you may ordinarily, may also help.
Sport insoles and orthotics should be worn for approximately 6-12 months before being replaced. If you are still experiencing discomfort or pain then it is recommended that you speak to a chiropodist, podiatrist.
