With a weight saving design and responsive midsole, the Saucony Women's PowerGrid Breakthru Running Shoe has all the ingredients to shave minutes off your mile during your everyday runs. With an 8mm drop and weight of 7. 3 ounces, the Breakthru is Saucony's lightest everyday trainer. The sublimated upper is composed mainly of a breathable mesh material with minimal overlays to save on weight. On the inside of the shoe, a moisture wicking material keeps your feet dry from sweat. A firm and fast midsole makes for a smooth and responsive feel, while a proprietary EVA material helps to shave some extra weight from the package. Since it is a trainer, the Breakthru features a durable carbon rubber sole to increase the life of the shoe, mile after mile.
