Flat footed?  These will definitely help.
I have flat feet and tend to pronate as well so I need support.  I wear an 8.5 women's medium.  I find that the RooRun insoles are the best for my feet. I have a pair of Wide width shoes (bought by mistake but I'm glad I kept them) and the extra width in the shoes is taken up nicely by the RooRuns and they feel like a regular width shoe again.<br />Again: great insole but if your shoes are already snug with the factory footbed liners that are in there, these might make it impossible for you to get your foot inside.
