Pros: Yes, these are really cute shoes. So cute, I think I'll get a another color. Plus, my orthotics fit in the shoe. True to size.

Cons: These are comfy but NOT supportive. There is zero lateral stability in these shoes. So forward is fine (walking or jogging), but in a high-impact aerobics class these might not be for you.

Revision: I took my orthotics out of the shoes and now I have more nice things to say. Surprisingly, these shoes still support my flat feet. Not as well as the orthotics, but I can get through an hour of low impact aerobics easily and without foot pain. The shoes do feel supportive in side to side movements and provide good traction on the floor.
