We loaded the Revolution 7 with the sort of soft cushioning and support that might change your running world. Stylish as ever, comfortable when the rubber meets the road, it's an evolution of a fan favorite that offers a soft, smooth ride. Foamy Ride - Foam midsole delivers a soft, smooth ride. Touch Points - Touch points at the tongue create a natural feel as you take off. Grippy Outsole - The outsole has a generative traction pattern that combines with rubber lugs to help give you grip when going uphill or downhill. What's New? - More room in forefoot compared to Revolution 6, so your toes don't feel pinched. Puffs added to the heel are visible on outside of shoe. They're soft to the touch and help add comfort to your Achilles. Product Details - Weight - Approx. 229g/8.1oz (Women's US 8). Heel-to-toe drop - 10mm.
