Orthotics are great! However, one size doesn't fit all -- what works for one won't work for another. Some can buy off the shelf orthotic inserts and some need custom fit. Unfortunately, you just have to try some and see how they work. I would recommend trying off the shelf first - custom orthotics are huge investment and may not be necessary. Also, it is a good idea to break them in for short periods of time each day before going for a full day in them. I have had good results with Orthaheel shoes. You may have better luck with another brand. When you find the ones right for you, you should definitely see a difference being on your feet on concrete.
