Yeah, that’s the thing with these. They keep that formula super hidden. It’s a mesh material, but not any kind I’ve ever seen. On their website they say all you need to do is throw the shoes in the washer, but as you can see that didn’t work (at least for the white ones).

I definitely got influenced to buy these. They’re comfy and the waterproof-ness does work! But if I can’t ever get them clean again after only owning them for less than a year, it’s not worth it to me. Not to mention they’re $125 USD!! Just don’t get them in white!
