Tangent… but for sweaty feet, try a ski boot dryer!

You can get them for $50… they dry out my shoes which makes them last a lot longer before they get so smelly I have to throw them away. Plus, who doesn’t like warm shoes in the morning?

That, and there are some creams called Sweat Block or whatever you can rub on your feet which reduce sweating. Those work as well.

Also try wearing merino wool socks. It seems counterintuitive to put wool on your sweaty feet, but they're quite comfortable and they help you avoid that "clammy feet" feeling when you are sweating in cotton socks. They also don't develop odor the way that cotton does.

You can also 3D print them: https://www.printables.com/model/194340-60mm-radial-fan-boot...
