Carrie,
I'm not sure if you are asking me or Cathe but if it was me, and I could still get the Rhythm II's in my size, I would stick with them. I wear a very small size and I looked and looked and couldn't find them anymore.
But this is JMHO, you might like them better than the Rhythm II's. The difference, I notice, is in the insole. The Rhythm II's insole is so "bouncy" and comfortable.
