Hi Karen,
I am not Cathe :>) I am not using the hc series yet. Too new for that.
But I did ask on the board about suggestions for shoes. I tend to have a wide foot and like my shoes to be comfy.
Quite a fee of the gals posted they used Ryka Enlight 11 and I must say, I ordered them online and got a great price and free shipping. They are by far the best shoes I have used. Here is the site for the shoes in case you want to check them out. http://www.onlineshoes.com/default.asp
