I did win a free one from a scratch off ticket in the package which was shipped fast and I received it yesterday, so I now have a backup if this one fails. Very very worth the money, fast shipping. I was hopeful that this product would work! This item has not met any quaility standards as far as I can see. Perfect for those that don?t have a lot of space. I have seen several people walk by the car when this is rigged and take pictures. It is much less expensive then what I purchased in the doctors office and works considerably better. Cute and comfy shoe. PIECE OF JUNK! Im a standard size 8.
