They are not too bad for the price
They are pretty comfortable and do a decent job of support for short periods of time or for really casual wear.  i would not recommend these insoles if you are on your feet all day or if you are hoping to use them for physical activities.  It is a pretty cool concept that you can add as much or as little support as you need.  Overall, they are pretty good but personally I would spend just a few bucks more for one with a bit more support.
