Here's what I've tried:
1. Anywears: comfy but lack of support hurt my back. Feet were fine, back ached.
2. Nursemates: semi-comfy but hard to walk in as mine are clogs. Not comfortable enough to want to buy another pair with a heel to try.
3. Dasko: by far the best for my back. My feet were pleased for the first couple of months. After that, the hard sole made my feet extremely callosed, so now I can't walk on hard floors barefoot without pain. Even getting in the shower in the morning hurts. I've tried creams and pumice stones, it's getting a little better, but not completely resolved. I tried inserts, too much arch support.
Any other ideas?
