The GEL-NIMBUS 23 running shoe continues to offer excellent comfort and long-run impact absorption. Its improved stability provides a more balanced stride that's followed by smoother transitions.Constructed with comfort and breathability in mind, the upper features a softer engineered mesh design for long runs. Engineered eyelet shaping helps the upper move more naturally with the foot, while a stretchy midfoot panel appropriately hugs the foot to generate better flexibility.
