Nike Pegasus 41 vs Pegasus 42

The Nike Pegasus 42 has a few noteworthy updates to the Nike Pegasus 41. There's an extra milimeter of stack height in the 42, and its toe box is more tapered between the ball of the foot and the toe. The 42nd version also has a new outsole pattern, which replaces the classic waffle design, and leaves more of the midsole foam exposed. Most significantly, the 42nd version has a full ZoomAir unit, instead of the the two ZoomAir pods that were in the 41. This change does make the 42 less susceptible than the 41 to causing discomfort if you land on the wrong spot, and the 42 feels more comfortable when you are standing or walking, but any added cushioning quickly disappears once you start running. Despite Nike's claims, the Pegasus 42 does not have significantly more energy return than the 41.
