While I agree with the comments in this thread, the how comfortable or supportive a shoe feels will range widely amongst individuals. I have foot issues yet Vionic is not as comfortable for me as Clarks. I speak particularly of Clarks Unstructured which do have support features in addition to the spongy comfort built into the footbed. My feel feel fine with Earths brands too.
Unless Cherjoy chooses to limit the options to Clarks or Vionics, and purchasing from QVC, there are dozens of brands comfortable more than both. Some of those brands are in the same price range as both. I suggest a trip to Nordstrom's shoe department which sells Clarks and Vionic along with some of the other brands I am referring to so that you can try on in store. If you don't have a Nordstrom try your local Macy's. You may find something you like and may still be able to buy that brand from QVC if that is your preference (Alegria for example which feel great on my feet).
