These Air Zoom Pegasus 38 Running Shoes by Nike continues to put a spring in your step, using the same responsive foam as its predecessor and a Zoom Air unit for an ultra responsive feel. Breathable mesh in the upper combines the comfort and durability you want with a wider fit at the toes, while the mesh in the upper feels breathable and plush while stretching with your foot for a comfortable shape and fit. The Nike react foam is springy and durable, more foam means more cushioning but without them being bulky and the Midfoot webbing gives a snug fit when you tighten the laces.
