Cloudlift insoles for a supercushy, ultrasupportive fit that feels like walking on a... well, you know. They're also as eco-friendly as we can make them. The cotton lining and rubber outsoles? Both recycled. Oh, and the leather is sustainable too. Please note: these sneakers fit slightly narrow, so we recommend going up a half size if you have a wider foot. Lining is 65% recycled cotton/35% conventional cotton. Outsole is 40% man-made/35% recycled rubber/20% natural rubber/5% rice husks (aka the speckles). Item MA503
