S: Kanye's partnership with Adidias. Kanye is a big songwriter, rapper, entrepreneur, and recently turned fashion designer, and Adidas being a global brand makes the perfect partnership.
W: The amount of demand that they don't supply. Adidas hasn't made a lot of the shoe. So that's why the demand and hype of the shoe is so high. Also the fact that Kanye's fans are crazy about the shoe because it's his shoe. The shoe has a new technology called "boost" which is the sole of the shoe and is what you're stepping on.
O: To supply more amount. They could fix that by just making a lot more of the boost and the actual shoe. Also Yeezy needs a lot more marketing and promotion of the shoe.
T: Jordan & Nike. These two brands are the biggest threat Adidas has faced and continues to.
