Madonna's pop-up shoe boutique has been the "most successful" of its kind for Selfridges.

The '4 Minutes' hitmaker's Truth or Dare collection is outselling the retail spaces of Aldo Rise, United Nude, Swedish Hasbeens and Marc by Marc Jacobs in the London department store.

Shoes buying manager Helen Attwood said: "It's been thrilling to see our customers' response to this project - the Truth Or Dare collection has proven to be our most commercially successful footwear pop-up this year so far.

"It's one of the most successful celebrity endorsements we've ever worked on."

Selfridges launched the Truth Or Dare collection just over a week ago, with some styles already selling out. The range, which comes in a monochrome colour palette, features all from flat brogues to towering platforms and stiletto boots."

The range has been so popular, the store have had to re-order several items from the collection.

Helen added: "We have already had to re-order on almost half the styles we carry.

"Bestselling styles have been the Panu studded court shoe and the Cedia brogue in black."
