If you have certain health conditions, the Nhs provides bespoke orthotics from a podiatrist without charge to you.
Ive had them before but they were extremely bulky and really uncomfortable. I think the waiting time will be very long and it's a waste of their time and money if I don't use them because they are uncomfortable.
I bought some in Boots today for 12.99 but havent tried them yet.
