Sportswear company Puma is to incorporate new, environmentally friendly insoles from Ortholite into the manufacture of many of its footwear lines.

Ortholite said the German company would become the first major brand to use its Ecoortholite technology in one-third of its footwear by the beginning of next year.

Ecoortholite claims improved breathability, moisture control, anti-microbial properties and long-term cushioning.

Ecoortholite uses a non-food source bio-oil as a substitute for traditional fossil fuel-based raw materials, replacing 20% of the petroleum normally used in the polyol component of urethane foams.

The move is part of Puma’s plans to meet a target of 50% of international collections manufactured according to its sustainable S-Index standard by 2015.

The styles using Ortholite will be identified through a logo carried on the shoe insole.
