Sustainable Materials

​​Sustainable products start with sustainable materials. Our goal is to source materials that have a lower impact on the environment whenever possible. 

Alterre sustainable women's shoes made with recycled plasticRecycled Plastic

Pellets made of plastic waste created during the shoe making process are melted and recycled to create all of our heels and shoe lasts. Since standard stilettos require virgin plastic, we create block heels or exposed stilettos so that we can use this recycled material.

Customizable shoes made with recycled denim - AlterreRecycled Denim

PET bottles from recycling centers are classified, washed, chopped and recycled into the polyester thread that is used in our denim. 40 plastic bottles create 1 kilogram of thread.

Sustainably sourced leather shoes - Alterre interchangeable shoesTraceable Leather

We source all of our leathers in Brazil so that we reduce our carbon footprint. Many of them are sourced from a sustainable Brazilian supplier called Courovale, who is LWG and CSCB certified. Courovale produces traceable leather and recycles their production waste. Water is also separated from liquid effluent and re-used when possible, reducing their use of surface water. 

chrome-free black leather - sustainable materials, ethical shoesChrome-Free Leather

Our black and white leathers are chrome-free, which means that they were tanned without chromium. This means it reduces chemical pollution into waste streams from the tanning process and improves biodegradability.

deadstock fabric - reclaimed materials, sustainble shoesDeadstock Fabric

We try to source deadstock fabric when possible. What is deadstock? It is leftover fabric that we reclaim from other brands so that it doesn't get discarded. The isn't much fabric left usually, so our deadstock shoes are always limited edition.


We Value Transparency

Where do our materials come from? We believe that corporate sustainability isn't possible without transparency.
