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. 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. Also, a gender-specific TRUSSTIC� device provides an articulated amount of support in the right direction for men and women to help generate a smooth transition. Under the toe, the inclusion of gender-specific pillars help cushion the body and help runners experience a softer feel. Simultaneously, the ORTHOLITE� X-55 sockliner equips runners with a forgiving, yet responsive stride. The components of the GEL-NIMBUS� 23 shoe help increase the softness without forgoing the integrity of the shoe's ride. Our 23rd version of the GEL-NIMBUS� continues to make advancements within the lineage by offering improved support and comfort for distance runners.
