A few different companies. I found the differences interesting:
The adidas Group strives to be the global leader in the sporting goods industry with sports brands built on a passion for sports and a sporting lifestyle.
Our mission is to become the best sports brand in the world. To that end, we will never equate quantity with quality. Our founder Adi Dassler was passionate about sports. For Adi, the athlete came first. He gave those on the field, the court and the track the unexpected and the little differences that made them more comfortable and improved performance. This is our legacy. This is what the brand stands for. This will never change."
Under Armour (in all caps):
TO MAKE ALL ATHLETES BETTER THROUGH PASSION, SCIENCE AND THE RELENTLESS PURSUIT OF INNOVATION
Reebok's mission is to always challenge and lead through creativity.
At Reebok, we see the world a little differently and throughout our history have made our mark when we’ve had the courage to challenge convention. Reebok creates products and marketing programs that reflect the brand’s unlimited creative potential.
PUMA has the long-term mission of becoming the most desirable Sportlifestyle company.
ASICS, an acronym derived from the Latin phrase, Anima Sana In Corpore Sano - a sound mind in a sound body. Staying true to the philosophy by which it was founded, every ASICS innovation, every concept, every idea is intended to create the best product. Our mission is to become the number one brand for the sports enthusiast. To accomplish this, we pledge to continue to make the best product; striving to build upon our technological advances and pushing the limits on what we can learn from the body and its needs in athletic gear. We pledge to bring harmony to the body and soul.
