Payless Shoes today announced the launch of a new eco-friendly brand called Zoe & Zac. The new line is mostly for adult women, but also features three girl’s shoes, as well as a range of jewelry and socks — all available for under $30 each.

The Zoe & Zac products are green because they are made from eco-friendly components and materials such as organic cottons and linen, natural hemp, recycled rubber outsoles, eco-friendly-EVA cushioning, and water-based glues for the shoes. Natural materials like dyed Tagua and Acai nuts are incorporated into the jewelry. The product packaging is eco-smart as well, utilizing 100 percent recycled shoe boxes and soy-based inks for the printing.

In celebration of the launch, Payless will also be participating in The Nature Conservancy’s Plant a Billion Trees campaign. The company will donate $1 — the cost to plant one tree — for every Zoe & Zac green brand item sold through May 4 and on every Payless exclusive reusable shopping bag sold throughout the year. The Nature Conservancy hopes this effort helps them reach their goal to plant 1 billion trees by 2015 to help rebuild the Atlantic Forest in Brazil.
