Even on the topic of financial influence...it's such a difficult thing to fully gauge. Because 'Ye won't get credit for ZX Flux, Tubular or Pure Boost sales, though it's no coincidence that adidas has 3 of their hottest silhouettes in years after the Kanye co-sign. Or something like boutiques getting adidas accounts because they want to be able to stock Kanye product.
Also for Nike, who continues to drop Yeezy-inspired colorways of their shyt to make money. None of that directly credited to Ye.
We know Ye is a factor in sneakers. I hope adi moves forward with a wide release of something soon.
