I have corns that will not go away! i change my shoes daily and have seen a podiatrist! what else can i do?

Corns: Corns develop in areas of increased pressure and friction. Reducing the pressure should help prevent recurrence. If you've been doing this and they keep returning, the cause may be from a bony prominence in your foot. A small surgical procedure can remove that. Also, other skin conditions can look similar to corns. A biopsy may be warranted to get a difinitive answer.

Surgery: You might need to get evaluated for surgery. See you local foot doc.

A podiatrist : Should of offered you both conservative treatment = trimming the lesions, and surgical treatment = shaving or cutting away the offending bone.

Depends on the cause: Many things can cause a thickening of the skin. Causes may include: viral infections (warts), friction, pressure, repetitive trauma, and a limitation of joint motion. Some genetic conditions may also cause people to develop calluses on the hands and the feet. Treatment depends on the cause of the problem. Have it evaluated by a professional and get the appropriate treatment.
