These are a great shoe, light weight and good arch support. I most probably used twice if that as I had to stop running and completely forgot they were in my closet ! In excellent condition. From Nike : The women's Nike Air Zoom Pegasus 38 is a light and nimble workhorse for your training. Nike built the Pegasus 38 around a bouncy React foam midsole. The material is popular in Nike running shoes because it provides premium cushioning while maintaining a springy ride. Designers added an extra pop to the ride with a Zoom Air unit in the forefoot. The pocket of air provides extra cushioning without extra weight, and it rebounds quickly for a snappy response when you take off. An engineered mesh upper is light and breathable, and midfoot webbing helps create a finely tuned fit. Nike shaped the toe box for a slightly wider fit this year, which makes the Peg more comfortable when the miles start adding up. With a durable rubber outsole that improves your grip on pavement and smooths out the ride, the women's Nike Air Zoom Pegasus 38 delivers high performance under an iconic nameplate.
