• 1. Smooth transition: We extend DNA LOFT beyond the heel all the way to the forefoot to maximize the Segmented Crash Pad's ability to deliver a smooth transition from heel to toe so each stride is buttery smooth.
• 2. Holistic Support System: We’ve shifted our focus beyond the feet to the most injury-prone part of a runner’s body: the knees. GuideRails® support keeps you moving comfortably by keeping excess movement in check.
• 3. Soft, secure fit: The new Engineered Air Mesh upper hugs the foot for a secure fit whlie also improving breathability.

For runners looking for a supportive shoe that's soft and smooth, the Adrenaline GTS 21 offers an improved ride and reliable support for however your body moves so you can forget the shoes and enjoy the run.
