The 'core black' colorway was introduced in June 2015, along with the 'silver' and 'white' versions. This particular design showcases a combination of black and grey on its Primeknit upper, featuring a black three-stripe cage and black flat laces. The heel cup is also black and includes silver and gold branding. The midsole is white Boost, providing enhanced comfort, and the outsole is made of black stretch web rubber.
