Buyer beware is the best piece of advise. There are many companies making a lot of money off people at trade shows. Research the company and know what you are getting before you buy.
Customized. Custom made and customized foot orthotics are not the same product. Trade show vendors are able to be profitable by slightly altering premade shells and selling "custom made" orthotics in one hour. Charging $250 -$500 for a pair of pre-made insoles manufactured in one hour is very profitable.
Education. Many trade show companies provide in house training (as little as one weekend) and provide their employees with a "certificate" for fitting orthotics. Do they really understand what this does to your alignment and posture?
Follow up. Trade show vendors are moving from city to city so you never know where they will be next week. Consumers need to be wary of what they are buying. If you are interested in foot orthotics, talk to your doctor or visit us for more information.
