Looking for Answers about Nike Air Pegasus + 29 - Men's?

The Air Pegasus+ 29 brings the cushioning and ride that neutral runners expect from this legendary Nike running shoe, with an even better fit. A breathable engineered mesh upper provides ventilation and support where you need it most. External heel counter wraps the heel for a snug, secure fit. Welded, ultra-lightweight underlay wraps the forefoot for flexible support. Fitsole sockliner conforms to the shape of your foot and offers comfort and underfoot support. Premium Cushlon midsole works with a Nike Zoom™ unit in the heel for soft, responsive cushioning and great forefoot flexibility. Integrated and articulated crash pad with horizontal side cuts works to absorb the initial shock of impact and smoothes the transition from contact to midstance for a uniform ride. Environmentally preferred rubber in a Waffle® outsole is durable and gives great multi-surface traction with a measure of added cushioning. Rubber blades on the lateral outsole act as a cushioning device by folding down at contact for a soft, smooth transition. Flex grooves are deeper along the lateral side and more shallow on the medial side to promote a natural, smooth, and efficient stride. BRS 1000™ carbon rubber along the heel contact zone delivers maximum abrasion resistance in this high-wear area. Wt. 10.0 oz.
