From Whistles comes the Ko shoes, a stunning and fashion-forward take on a menswear staple. Giving a feminine edge to the traditional derby model by combining it with wedge stylings, this contemporary shoe utilises a cleated outsole, beautiful fabric linings, an almond toe and crisp lacing. Set to capture attention, the Ko is ideal for the more daring fashionista. Team these with a knit jumper and ankle-length trainers for a cool outfit. Heel height: 6cm Brand : Whistles.
