The Nike brand is simply one of the best brands in the world...it may be thee best brand in the world...although that's a matter of opinion. Personally, I run in Asics shoes because of the stability, but many, many, many people swear by Nike. I also should mention that 75 percent of my running gear (shorts, pants, tops, hats) are Nike. Why? Because Nike is synonymous with style, quality and functionality. Their products look good, last for many wears and actually work. Take the Nike Dri-FIT product for example. I have several Dri-FIT shirts and I will keep buying more because they actually work.
One more thing I want to mention about Nike is that they know their audience and they have this amazing ability to target them. Back to the new running commercial...only Nike could develop a spot so emotionally and theatrically realistic to its running customers. Kudos to Nike for developing one of the coolest most innovative brands of all time and to the Nike agencies who again and again demonstrate the power of great creative.
