Synthetic sole Ortholite Sockliner - Moisture management (Ortholite is a registered trademark of ATP Manufacturing LLC). Guidance Line Midsole Technology - Vertical flex groove decouples the tooling along the line of progression for enhanced gait efficiency. The GEL-CONTEND 7 running shoe provides excellent cushioning for runners seeking a combination of durability and support. Designed with an engineered mesh upper, this application stretches with the foot's natural motion and creates an excellent fit. The synthetic stitching on the overlays helps create a more supportive foothold. By following a more sustainable design approach, this shoe also uses fewer resources to color the sockliner. The reliable cushioning stems from rearfoot GEL technology, a durable AMPLIFOAM midsole, and an OrthoLite sockliner that are each designed to improve comfort and provide excellent shock absorption. Following the natural progression of the foot, GUIDANCE LINE technology helps generate a more natural and consistent stride. Additionally, the flex grooves in the outsole increase the shoe's flexibility during your step—creating a more natural feel from footstrike to toe-off.
