Sanuk, a division of Deckers Brands, today announced the fourth iteration of its collaboration with rock band, Grateful Dead, powered by Warner Music Artist Services.

As an evolution of Sanuk's sustainability journey, the men's and women's collection utilizes the power of natural resources like algae and pays homage to the band's legacy with custom tie-dye patterns and the Grateful Dead lightning bolt logo in Sanuk's most popular styles.

Building off Sanuk's previous trio of capsule collections in partnership with Grateful Dead, this next iteration features new pastel and muted custom tie-dye colorways decked out with the band's 13-point lightning bolt logo across the Sling, Sandbar flip flop, Donna and Vagabond Sidewalk Surfer styles.

Special guest details in the collaboration include embroidered patches, embossed emblems, band tags, jute outsoles, premium footbeds and step-down heel counters. Added to the set list, Sanuk's new Bloom x Soft Top Foam technology delivers the utmost in cushion, high rebound bounce and support across the collection's kicks for the comfiest trip to your happy place.

This collaboration features Bloom Foam, which uses repurposed algae.  The use of Bloom Foam cleans approximately 2,800 cubic meters of air while the inclusion of other natural materials like hemp, jute and responsibly sourced leather together saved 21.6 million liters of water.  Sanuk was also able to reduce greenhouse gas emissions by more than 20 percent per pair, equal to 78,000+ miles driven by the average vehicle.

"Creativity, collaboration and music are crucial for us all – especially during these unique times," says Seth Pulford, marketing director, Sanuk. "We're excited to pay tribute to the band and the magnetic legacy they've gifted us with. This collection of modern classics does just that."

The fourth installment of the Sanuk and Grateful Dead mashup is available now.
