Product Detail Sneakers that free your feet ? to flex, breathe, and move without feeling weighed down ? here in a luxe winterised version. On top, they sport uppers in a mix of soft, warm, superfine merino wool (naturally thermoregulating, moisture-wicking, anti-microbial) and PET nylon (recycled from plastic sea waste) for durability. With suede heel detailing and logo'd pull tabs giving easy on/off. Underneath they're biomechanically engineered with our featherlight, ultra-flexible Anatomiflex™ midsoles that move with your feet. Wear yours indoors/outdoors, they're cosy, comfortable, eco-conscious.
