Ballet shoe brand French Sole has announced a new collaboration with luxury English womenswear and accessories label Beulah London to launch a limited edition 'Blue Heart Shoe' in aid of the Blue Heart Campaign, supporting the UN Global Fund for victims of human trafficking. The French Sole style loveheart shoe is transformed in grey suede with a signature Beulah blue heart lining, while the blue velvet heart covering the toe complements this. 25% of the profits made from each pair sold will be donated directly to the campaign. Due to be released in December, the limited editions will be available in the King's Road or Brook Street stores and the brand's website, priced £185.
