I was searching online for orthotic-friendly ballet flats (contradiction in terms!) and I found mention of this OTC orthotic insert that is supposed to work in flatter shoes with not a lot of room. Has anyone tried it? I think I may check them out. I have Rx orthotics but they basically fit in nothing except my sneakers (and they're the slimline kind!).
