Frankly, I was very disappointed when Costco stopped making custom fit orthotics a number of years ago. Those originals lasted a LONG time.
Our podiatrist suggested we go to a physical therapist to get custom orthotics. The cost was huge at $750 each and then we discovered the company they ordered from only kept our "foot molds" for a year. In this day and age of electronic scanning, this made NO sense to me.
When the "custom" orthotics finally gave up the ghost, we had them refitted by a local shoemaker, but we were not satisfied with the result. Very fortunately, I took one last stab to see if Costco might once again return to the orthotics business. I was THRILLED to find Orthera's website and that they had my original Costco orthotics on file. I ordered TWO sets as well as another set of non-custom orthotics from the Orthera website.
Orthera's customer services was exceptional - they communicated with me from the get go as to the status of the order and inquired for clarification to make sure they got the "right" orthotics for me - I had two different styles in their system. The orthotics arrived in about a week - which I felt was fast. I installed them in my shoes immediately and cannot be happier. They fit perfectly into my shoes with NO alteration whatsoever. (the "custom" had to be trimmed to fit!)
I've now worn the Orthera (Costco refills) for several weeks and I am totally satisfied. This is a tremendous product/service to Costco members like me who were/are extremely satisfied by the original product. And the price point is VERY reasonable, lending the product well to replacing every few years via normal wear.
One bit of advise should you order - and I think you should - sign up for the 15% off you will be offered when you go to place your order. I did not originally as I did not realize it was an offer from Orthera - as it says: "....who does not want to save 15%??"
Happy Feet! Thank you!
