Ladies, if you have never tried on a ryka shoe, I would encourage you to do so! They are made with the woman in mind. I now own four pair: Radiant (for serious walking), Rocker (for day to day walking and toning), Aqua fit 3 (for jogging in the pool), and Studio D (for Zumba)
ryka.com if you can't find them in stores. Locally, I get mine at Tradehome.
