Nisolo offers you the sock-like comfort, machine-washable, and sport-inspired sneaker that raises the bar for sustainability. These comfy shoes for women are ultra-lightweight with easy, slip-on construction. We only use recycled rPET materials made from plastic water bottles which make our shoes green and sustainable. They have a soft, cozy interior, making socks optional. They are also made with water-resistant upper materials and waterproof outsoles for protection from the elements. We’re committed to using recycled materials, and we hope you are too!New in box
