Running is good for the body and soul. Science has proven that endorphin rush improves mood and brain function. The recent resurgence of avid runners has driven the need for the next generation of shoes engineered specifically to handle the constant ground-pounding. Women's feet are different from men's, so running shoes are developed and fabricated with that in mind. Shock absorption, sole wear and stride variance are vital. Wearing the shoes with the right fit can be the difference between short sprints and marathons.
