I’ve had good luck with the Whitin brand on Amazon. I’ve been wearing their shoes for daily wear for about three years.
For running i have really like the 5mm Topos I bought last year.
I’ve heard, and my wife can confirm, that crocs are actually pretty good zero drop shoes with a fair bit of cushion.
See? In all the searches high and low, I haven't heard of topo. Good to know. But I assume these are not flexible enough to be able to bend into a ball cuz they have thicker soles, right?
I just discovered them by chance because they had them at the local running store.
As far as flexibility, I’m not sure how flexible you want. They defiantly have a legit sole. I’ve not tried all their models, so they might vary. Their big thing is the wide toe box, not necessarily zero drop or minimalism. But I tried to roll them into a ball and this is as best I could do. Lol
