The Pegasus 42 is Nike’s latest take on one of running’s longest‑lived daily trainers—built to feel lively underfoot while staying grounded where it matters. It keeps the everyday comfort the line’s known for, but flips in a full‑length Air Zoom unit that gives it noticeably more pop and energy return than before.

The engineered mesh upper feels lighter and more breathable, wrapping your foot without making the shoe feel stiff. Underfoot you get a ReactX foam midsole paired with that curved, full‑length Air Zoom unit, tuned to deliver a springier toe‑off and a smoother transition from heel to forefoot.

Fit feels a bit more roomed out up front compared to past Peg models, with a slightly wider forefoot and a toe spring that keeps things rolling. The modernised waffle rubber outsole still grips roads and pavements while playing nice with the cushioning underneath.
