In London, household name designer Calvin Klein is using fibers from pineapple and wood wastes in its debut trainer footwear.

“The Sustainable Knit Trainer” features a knitted upper composed of Ananas Anam’s PIÑAYARN® blended with Lenzing’s TENCEL™ Lyocell fibers. Crafted through a low-impact manufacturing process, PIÑAYARN® harnesses the potential of pineapple leaf waste while employing a water-free spinning technique. The inclusion of TENCEL™ Lyocell, a fiber sourced from responsibly managed forests and produced through a solvent spinning process with a remarkable solvent and water recycling rate of over 99%, ensures complete traceability of TENCEL™ fibers within the blended yarn.

The casual shoe is available in in classic hues, including black and off-white, with the iconic Calvin Klein logo.
