Grammy-winning rapper Kanye West‘s successful Yeezy Boost sneaker launch this year has resulted in strong overall sales for sportswear company adidas.

According to reports, adidas CEO Herbert Hainer credited Ye’s kicks for strong first quarter sales in a conference call this week.

“Moreover, at the launch of the Yeezy Boost, our first shoe developed in collaboration with Kanye West, long queues formed in front of stores. And let’s not forget the success of the newly launched Tubular and the latest version of the ZX Flux. All of this drove an aggressive 29% sales increase at adidas Originals, with strong double-digit increases in all markets, except Russia.” (Sole Collector)

Earlier this year, Kanye revealed he had no intention of putting his adidas debut kicks out for a limited run and at $350 per pair.

“I didn’t want them to be limited, that’s something the company did,” Kanye revealed. “I really want as many people as possible to get them. I didn’t want the price to be 350 [dollars], I don’t want to play this sneaker culture game with costs and they’ll be re-selling them for high prices and stuff. I just want people to have what I make. There ain’t no limited release of The College Dropout [album] – I think with clothing right now, there’s real separatism.” (“The Breakfast Club”)

Despite being released last winter with the $350 price tag, the kicks were auctioned off for more than three times the actual price online.

The initial Yeezy Boost release was limited to the New York area and a global launch is scheduled for February 28th, and although it will be among the most difficult sneakers to get your hands on, you’d be certifiably insane to not at least try and snag them for retail before wasting upwards of $1,500.

Recently, G.O.O.D. Music star Big Sean talked about Kanye putting together a solid adidas collection.

He showed off the $350 sneakers and praised his mentor for his innovation. “Shout out to ‘Ye for not just executing the shoes, the clothes were really great,” said Sean. “I’ve never really seen a fashion show presented like that. … He changing the game as usual. Proud of my big bro, proud to be a part of a team that really cares about quality and just making a difference.” (Rap-Up)
