I'm wondering if this will damage the shoe somehow. The shoe doesn't include washing instructions. My shoe actually has four materials listed, they are:
-Polyester -Polyuretan -Natural rubber -Nylon
I don't know any chemistry, I'm ignorant. I think this substances can come in many forms, so there is a lot of uncertainty. But if you answer for at least what the title asks, I'm fine, I'll make more questions for the rest of the materials.
