Carrie Underwood just dealt a big blow to Adidas

Adidas has been losing market share to competitors like Under Armour and Nike.

And now, the brand counts country star Carrie Underwood among its competitors.

Dick's Sporting Goods will remove women's clothing items from Adidas and Reebok to make room for Underwood's Calia line, reports Sara Germano at The Wall Street Journal.

The Calia line, which includes leggings, sweaters, sports bras, and headbands, will be sold exclusively at Dick's, according to WSJ.

Dick's move is an attempt to cash in on the "athleisure" trend pioneered by Lululemon of wearing your gym clothes to work and brunch.

Nike and Under Armour are also pushing for more female customers and expanding product lines.

Adidas executives say they are trying to regain market share by selling cool gear to young athletes.

Under Armour has surpassed Adidas to become the second biggest sportswear brand in the US by sales, the WSJ reported last year.

Under Armour reported sales growth of 20% to $1.2 billion, while Adidas' sales fell 23% to $1.1 billion.

While Adidas has been going after hardcore athletes, Under Armour has signed sports stars like Muhammed Ali and Stephen Curry.
