- Flexible upper in black—which means no break-in period, ever. - A contoured footbed and a terry-lined tongue for supportive structure. - Comfortable, adjustable laces in black for an optimal fit. - Sturdy white outsoles with grooves for added traction and durability. - Padded ankle collar cushioned with excess material to minimize waste. - Fully machine washable, so they're like new again and again. - Knit from Rothy’s signature thread, which is spun from single-use plastic bottles. - It took about 28 plastic bottles to knit this pair of shoes. Brand new in the box. Never worn.
