Green Leaf
The Green Leaf standard unique to New Balance highlights the presence of environmentally friendly materials. For textiles that meet this standard, 50% or more of the materials used must be part of an eco-responsible approach. This means they can come from recycled fibers or, as with cotton, from sustainable farming methods (such as the Better Cotton Initiative, for example).
