Fall '18's trend for 'ugly sneakers' isn't one to approach halfheartedly - you have to go full tilt or the irony gets lost. Worn on Gucci's Fall '18 runway, this 'Flashtrek' pair has been made in Italy from white leather, suede and padded mesh. They're decorated with removable crystal straps (although why would you take them off?) and have chunky lug soles.
