Ditsy Sun BLOOM™ Sandals. With thick lycra tactel fabric straps in seasonal prints paired with a comfy footbed and funky stripe running through the midsole, the Ditsy Sun BLOOM™ Sandals add the perfect finishing touch to any summer look. BLOOM™ algae biomass 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.
