Nike Pegasus 39 vs. Nike React Infinity Run Flyknit 3 (Comparison)

Nike Pegasus 39 vs React Infinity Run Flyknit 3

Both models are comfortable and versatile running shoes for daily runs (mid to long).

The Infinity Run 3 is more cushioned with a 34 mm heel stack height versus 28 mm for the Pegasus 38. The feel is firmer on the Pegasus 38, while the bounce is equivalent.

Stability is the main point of differentiation: the Pegasus is a classic neutral trainer, while the Infinity Run 2 aims to offer impeccable stability, especially for runners who overpronate.

Overall, runners better received the Pegasus 39, and we recommend it if you’re on the fence.
