I have been an Asics Girl for many years and decided to try these Brooks Adrenaline shoes. I have flat feet, had 3 anterior cruciate ligament surgeries and these shoes are awesome! They are great for both support and comfort. I took them to training a couple of times, but each time dark spots appeared on them. I like my shoes to look new so my next pair won't be white, they look great but get dirty pretty easily.
