The Billionaire Boys Club x Reebok InstaPump Fury Boost ‘Earth’ showcases verdant earth tones on a retooled version of Steve Smith’s iconic design. Light brown Cordura fabric makes up the composition of the upper, which replaces traditional laces with a green-hued synthetic cage. The inflatable structure is activated by a crimson pump button decorated with BBC’s signature spaceman logo. adidas’ Boost cushioning is utilized on the decoupled midsole, reinforced underfoot by a gum rubber outsole.
