Dune is launching a limited edition Sparkling Shoe in aid of Teenage Cancer Trust.

Available in stores and online from November 11, the design marks the fifth year of the retailer's collaboration with the charity, with £50 from every pair sold going towards funding specialist units, clinical staff and education programmes. Dune is also offering its Facebook and Twitter followers a chance to win a pair of the shoes, signed by Girls Aloud star Nicola Roberts.
