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. Additionally, the shoe's upper is made with recycled materials to reduce waste and carbon emissions. Providing the runner with excellent shock absorption and softness, the GEL-NIMBUS® 23 delivers more compression in the heel thanks to its softer GEL® technology cushioning unit and contoured design lines.
