As a performance running company, Ratio set out to create a highly sustainable performance running shoe, and we did. 

Our idea was simple yet innovative; the longer a product lasts, the more sustainable it is.

Ratio performance running shoes defy the odds. Most performance running shoes lose its maintained cushioning at 150 - 225 miles. Ratio shoes can last beyond 750 miles while still maintaining the necessary cushioning to protect your body. This makes our Ratio shoe not only more sustainable but also more cost-effective. Ratio offers a significant environmental benefit by reducing its carbon footprint.Ratio’s mission is to set a new standard in the industry by creating high-quality and long-lasting products.
