I went in here looking for running shoes for my casual running exercise program. The woman I dealt with did a gait analysis and pulled several different shoes built specifically for someone with my gait. She knew the types, brands and styles of each shoe by heart. She was completely knowledgeable of her inventory and knew exactly which shoes for me to try so that I didn't waste my time on the wrong items. And don't forget this is a specialty store. They cater to a sub-set who know what they want and need to remain injury free. And while the products are a little pricey (about $130 a pair), deals can be found so check them out. You may even learn a little something.
I recently bought a pair of Saucony Kinvara running shoes based on the analysis of how I run by the sales person there. She offered several shoes that would work for me before I chose this one. Very happy with the shoes and the service I received that put me in them.
