I think someone at Prada might have been having a laugh when they designed these. But if the high fashion version of shoes that light up when you walk (these don’t, FYI) float your boat, so be it. The ‘Levitate’ Shoe Series includes several classic silhouettes like the Plain Toe Derby, the Penny Loafer, the Wingtip and the Chelsea Boot, all made over with a transparent outer sole and dressed in metallic leathers. The whole range can be found at Nordstrom.
