John Carp/Mustard


Part of our Project Sustainability™ collection, the John Carp Mustard features our newest eco-friendly material innovation: carp leather made from grass carp fish. Grass carp are an invasive species in North American waters, so in working to reduce the carp population, we’ve created a palette of carp leathers to accent your favorite silhouette. The all-around white recycled leather and suede details are complemented by a mustard recycled carp leather heel tab and matching mustard recycled laces.

This pair features a speckled tread made from recycled mixed materials.

    Love the look, design and comfort of my P448s. Subtle but design elements that catch your eye. These go with many outfits. Comfortable from the first day I wore them.
