I bought these shoes w/ Zumba classes in mind.  The first night I wore them my feet felt like they were on fire.  The balls of my feet were burning, like standing on hot coals.  I thought maybe my feet were not being supported properly, so I took the custom fitted insoles from another pair of shoes and put them in the Asics.  Tonight's class was much more comfortable.  I think I'll have to have another pair of insoles fitted so I can have them in both pairs of shoes, an added expense I wasn't expecting.
