Are there cheap inserts that can help my plantar fasciitis and heel spurs?

Yes: Try dr. Scholl's orthotics. They can be found in any pharmacy for under $20.

Yes.: But they will not be custom-made for your feet, and they'll tend to break down in about a year or so, depending on how much you wear them. Custom inserts can last up to 5-10 years.

It is possible: Try over the counter arch supports, but you may need more supportive custom orthoces.

Possibly: Depending on your foot type, you may be able to find an over the counter arch support like "Power Steps." They do not work as well as a custom orthotics. Anything less than $30 will most likely not help. Consider seeking out a podiatrist for evaluation.

What is "Cheap?": I REALLY like the products from the Spenco Medical (www.spenco.com) company. I have many great results with my patients using these. The ones with the most support are in their "Ironman" series, but the Total Support and CrossTrainers work well too. I like my patients to get the most firmness they can tolerate. You should expect to spend between $35 and $50 for something GOOD!!!
