Customer review: “Vivaia’s shoes are made from recycled plastic bottles, which is what originally got me interested in the brand. I think we can all agree, 6 plastic bottles never looked this good…the first thing I noticed was the insole; these are now more cushioned and structured around the arches and toes.”
