Last Spring Nike Sportswear released the Nike Air Kukini, named after swift run­ning Hawaiian foot mes­sen­gers. The Air Kukini was actu­ally designed for triath­letes with its light­weight, breath­able and quick-drying mate­ri­als and the ease with which you can pull them on your feet. In this time and age of light­weight and min­i­mal run­ners, it comes as no sur­prise to see a Free ver­sion of the shoe, dubbed the Nike Kukini Free. Taking the upper of the Air Kukini and plac­ing it on a Free sole in vibrant col­ors makes this shoe a stand out next summer.
