Wrong size sent twice!
These have to potential of being a good insole, but the verdict is still out.  Ordered these twice and both times I received a size "M" instead to the "S" shown in the photo for women sizes 5 to 10.  The first time I thought maybe someone had just grabbed the wrong size but when I received the wrong size a second time I was a little discouraged.  I cut the second pair down below the smallest insoles indication, just to get it to fit in my 8 1/2 size shoes.  I'm sure the arch is not exactly in the correct place, but I do feel my arch being supported.  I tried using it in other shoes, but you really need shoes that have plenty of room in them, as they made my other shoes too tight to be comfortable.  Amazon really needs to get the correct size in or update the posting with the correct info.
