text: Hmmmmm I'm not sure if I'm using these wrong. It unfortunately reinforces my flat foot and it actually hurts wearing these. I put these in my Keds shoes and  I've been getting a lot of foot cramps, sometimes I can barely walk. It is true to my shoe size, but kind of upset that my ballet flats don't fit them when it should be...(my ballet flats are size 7.5 and I ordered the 7-7.5 insoles) so that's weird. *I bought this at a discount in exchange for my honest review.
