I'm under the impression that SF Green offer the most arch support. Sometimes I think I'd like something with a little more arch support. My feet are pretty normally arched.
Around 10 years ago Chaco, the company know for their rugged sandals, made fantastic insoles. I got a second free pair with a Chaco hiking boot purchase. Those insoles were purple and had a carbon fiber looking lower. They were really excellent. I used them for years.
