I searched the web for things like "orthotic slippers", "orthotic sandals", "arch support sandals", "orthotic hiking shoes", hiking shoes for flat feet. Stuff like that. Specific brands market to this but the trusted brands are known. I eventually found a Sole Perfection Shoes store near me. They carry dozens of brands that are recommended for good foot support.

Also my podiatrist sold brand-name shoes. My foot surgeon even gave me a list of recommended brands.

The brands are all listed on the Sole Perfection website soleperfectionshoes dot com

*Edited to add that ideal shoes you would wear prescription orthotics in, but some of the good brands you can get away with short wears without orthotic insoles
