This is an insanely cushy shoe! Minimalist in fit, for my medium arch there is almost no arch support in the insole (simple insole swap would help), but still super comfy. I'm just now slowly breaking it in and it's beginning to fit around my foot, so as it molds to my feet, the arch support is almost not an issue. I agree with other reviewers that this runs narrow and a bit long, but as it's more of a casual type shoe, tho I've just used it at the gym to weightlift in, it's stable enough for low/no impact gym activities.  So if you have medium width feet like mine, go a half size up. Will try this out for a Zumba class soon and update this then.

All in all a great, casual to kick around and use at the gym shoe. Again, thanks Amazon as I got these on sale here, they still are, and at that price so worth it.

Update:

  Had this for a bit now and I find I like using them at the gym a lot, got compliments on the color and it goes great with my gym clothes too. Ive used them for Zumba and I find it needs more forefoot cushioning for this, especially for some jumps, but for Street Dance/hip-hop this was fine for twists and turning. I wouldn't use this for any high impact class as there's not much stability for this. Still, this shoe has continued to surprise me with how versatile it is. Typical Asics too, it's already broken in nicely to fit my foot, but a 1/2 size would be better but I doesn't bother me that much anymore. I would love another pair in a different color but they're not on sale anymore so at this price point  I'm considering the Gel Blur 33 TR as a similar option.
