I have one pair of Ryka's that  I wear to work that are so comfortable.  I could not find that style of shoe, so I ordered the Ryka Intent X1 for work.  I broke them in gradually.  I decided to replace the removable insert with  a Spenco because the arch support was a little to high.  It worked and I wore them yesterday all day and they were very comfortable. Ryka's are about the only shoe I can wear comfortably because I have a B width toe and a AA heel.  I hope this is helpful.
