Flat Arch Feet Shoe Options

I’m trying to expand my collection towards sneakers, sandals, and boots that have strong arch support, don’t require orthotic insoles, and are versatile/easy to style.

I currently wear On Cloud Roger’s and New Balance 1906R for my flat feet, and love to walk 10k steps daily. I’m also open to wearing insoles for flat shoes, only if doing so really helps my arch.

What are some good recommendations?
