Yes, Hari Mari flip-flops ($60, harimari.com) are the most comfortable we have ever worn. Yes, they come in a bunch of cool colors. Yes, they are made with recycled and sustainable materials and have a solid one-year warranty. But here’s why we like our Hari Mari flip-flops so much: We know that with every pair sold, the company donates part of the sale price to help fight cancer in children. Now that’s a cause worth sinking your feet into. A bit pricey, for sure, but they’ll last longer than most cheaper brands, and you can be confident your money is going toward a good product — and a great cause.
