Continuing to evolve as part of a yearly cycle the Nike Air Vapormax 2021 FK Grey Lime places Nike’s revolutionary VaporMax cushioning on a slightly-modified version of the FlyEase-enabled VaporMax 2020. A year of further development has by no means reinvented the wheel, but instead continued to modify the existing formula to great effect. Coming in a lightweight but durable construction from toe to heel that boasts a colour scheme reminiscent of the Air Jordan 3 famed’Cool Grey’, the composition breathability is perhaps the most welcome returning feature. Aside from the base design gracing the majority of the iconic shape, this particular model features profile swooshes, pull tabs on the tongue and heel and plastic reinforcement around the forefoot and heel all of which deviate from the muted tone in favour of eye-catching hues of lime green and ice blue.
