Are there slides that are 100% rubber?

I’ve been trying to switch to more plastic free products where possible, and right now I’m looking for a pair of simple slides for everyday wear. Something comfortable, durable, and easy to wear around the house or for quick errands. While searching, I noticed that most slides seem to include plastic somewhere in the materials. Even when they look like rubber, the description usually mentions EVA, PVC, or some other type of plastic blend. I was hoping to find slides made from 100% natural rubber, but that has been harder than expected.

I’ve checked both in physical stores and typical online marketplaces like Etsy, Amazon, Alibaba, eBay, and even Facebook Marketplace. Almost everything still seems to rely on plastic in some form.

So I wanted to ask if anyone here knows whether fully rubber slides actually exist. Are there brands that make slides from 100% rubber or mostly natural rubber without plastic blends? If anyone has recommendations for specific brands or places to look, I would really appreciate the advice.
