Spend this summer in the Koosh Cross Over BLOOM Slides. The cross-strap design and soft brushed footbed promise all-day comfort. These sandals are made with 30% BLOOM algae biomass, which is a natural component added to the existing EVA of our sandal footbeds as an alternative material resource. BLOOM blends algae, harvested from environmental restoration and protection projects in North America and Asia, with non-biodegradable materials to maintain product durability and prevent the release of captured carbon.
