A pair of Nike ZoomX Vaporfly Next running shoes. These distance running shoes have a breathable Vaporweave upper, a material inspired by the lightweight, flexible and hydrophobic material use in racing sail cloths. The offset laces reduce pressure on the top of the foot and there is additional padding around the achilles. The outsole has been designed to provide improved traction in the wet. The shoes have a thick ZoomX foam midsole which is said to return 13 per cent more energy than more conventional foam midsoles and which some runners have reported reduces fatigue in their legs. ZoomX foam is a tailor-made low density thermoplastic elastomer combination of polyamide and polyether. Embedded in the midsole is a thin carbon-fibre plate which increases the stiffness of the shoe, stabilizing the ankle joint and reducing the load on the calves. Nike claims that the carbon-fibre plate saves 4 per cent of the energy needed to run at a given speed when compared with another of its popular racing shoes. The colours of this particular example are said to be inspired by Hakone's mountainous landscape and the Japanese bullet train. Complete with box and drawstring bag.
