Gently used. Never worn outside only in gym. Sadly just sitting in my closet. Lots of life left. Very comfortable. Purple, green, pink. This dramatic update takes the GEL-Sendai™ to a bold new level of performance. The GEL-Sendai™2 packs in features like FluidFit™, discrete GEL® Cushioning System, Heel Clutching System™, and Propulsion Trusstic®, yet comes in almost a half ounce lighter than the previous version. This high-tech ride is designed to accommodate gaits ranging from mild underpronators to moderate overpronators.
