100% authentic (juuuust like all my stuff). ZoomX VaporFly NEXT% 'Ekiden White Racer Blue' Never used because I had too many shoes. Bought under a period I was running and hoarded tons of running gear. This was years ago. Still sells for £140 online. They aren’t produced anymore so they are quite a rarity :)) Run and don’t walk! Buy them here today for a super reasonable price!!!
