The Billionaire Boys Club x Reebok InstaPump Fury Boost 'Earth' is a retooled version of Steve Smith's iconic design. It features light brown Cordura fabric on the upper, replacing 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. The decoupled midsole utilizes adidas' Boost cushioning, reinforced underfoot by a gum rubber outsole.
