I bought these extra-expensive foot supports last winter and they worked well. Now they are worn so I ordered what I thought was another pair - and in fact - what was advertised as another pair, same seller. But when they arrived, they are not the same. They have a different heel and sole design. These are not comfortable like the first pair I bought and no wonder - the design of the bottom is different.<br />The original pair said &#34;patent pending&#34; and &#34;Made in Korea&#34;. This pair has neither a patent number nor the words &#34;patent pending&#34; anywhere on the box or item. They do not say made in Korea. For all I know they are an EXPENSIVE KNOCK-OFF.  DO NOT BUY. If companies can't sell a consistent product including DESIGN and PROOF of authenticity, customers can find something just as good for a way cheaper price. I suggest you look around for a cheaper option, I'm sure it will work just as well. I want to know where ALL ITEMS are made. I don't need that much stuff that I force myself to buy things that may be ripping my own self off. This corporation is giving consumers the middle finger.
