The insole comes out, which is the reason to buy this one
Aetrex shapes their Signature Arch Support into the footbed rather than gluing padding on top of a flat board: a rise at the apex of the arch, a cupped heel. They say it's there to help relieve heel and arch pain.
The part that matters more is that it lifts out. Aetrex lists this style as Removable Insole: Yes, and their sandals, wedges and cork styles as no.
So this shoe isn't a finished answer, it's a platform. If the built-in support turns out not to be enough for your foot, you pull the insole, put a proper orthotic in, and keep the shoe. A dress-casual leather shoe that will take a prescribed orthotic is a genuinely short list, and it's most of why we stock these.
