For a run you can put your faith in, the Pegasus 40 is here, whether you’re out for long marathon miles, a speed session, or a quick group jog. The single layer engineered mesh upper gives improved breathability with the same Pegasus fit, while a mid-foot band hugs your foot for a more secure, but forgiving feel. Increased foam and re-worked paddings all improve comfort around sensitive areas of the foot, making those long miles even easier. The Peg 40 still features the same combination of durable, smooth, and responsive React foam, with Zoom Air units providing an extra propulsive boost in the heel and forefoot.
