Stretch-knit textile upper, similar to a sneaker knit, over a flexible flat sole. Hand wash in cold water with a mild detergent and reshape while damp, then air dry away from direct heat — this is one of the few shoes in the range that can actually go near water, since the knit is washable rather than leather. Stuff the toes lightly with a cloth or paper while drying to help the shoe hold its shape rather than flattening, and avoid the tumble dryer, which can shrink the knit and distort the herringbone pattern.
