There is information about the annual foot checks you should be getting here:
Everyone with diabetes should have an annual foot check. Your foot check is part of your annual review, which means you should have it as part of your diabetes care and it's free on the NHS. This is because you’re more likely to have serious foot problems and these can lead to amputations...

Including details of seeing a podiatrist, who would be able to help assess your foot health, gait, and recommend any orthotic support you may need.
You may be able to get a referral to a podiatrist or get seen at a foot clinic if you are at risk, but other members have found the system under quite a lot of pressure since the pandemic. Alternatively you may be able to book a private appointment with a podiatrist.
Good luck with your new menu, hope it’s soon starting to get things back on track for you
