You should be seen by a podiatrist. They can soften these callouses and remove them properly. You chance getting an infection when you pull off the skin yourself and have bleeding. Foot infections can be difficult to treat and you have a long life ahead of you - so have a professional do it. I do not trust nail salons to do this type of procedure (shaving) as I know some of them do it in my neighborhood. This is not an acceptable practice for anyone but a medical professional.
