The Dynafit Ultra 100 Women’s Shoe is designed for long runs, whether you are an ultra-runner or just out for a long training run. With lots of cushioning, the shoe boasts a precision fit while leaving sufficient room to guarantee the ideal blood circulation and prevent your feet from swelling up on long runs. It also features a 6-millimeter drop, which is most preferred by ultra-runners. With a Pomoca Outsole, you get tremendous grip and traction no matter what the surface conditions are like. And with Heel Preloader Technology, you get diagonal reinforcement that keeps your heel locked in the heel pocket, while also improving foot hold and overall fit. Invisible lacing offers extra protection against anything getting into your shoe, which is a truly great feature. For the female runner who's in it for the long haul, the Dynafit Ultra 100 Women’s Shoe is perfectly equipped to go farther than you ever thought was possible on your own two feet.
