YOUR RUN STARTS WITH STABILITY AND SUPPORT. Take the first step on your running journey in the Nike Downshifter 12. Its lightweight construction offers a balanced and supportive experience, making it perfect for both training and relaxing. As part of our sustainability journey, this style is made from at least 20% of its weight in recycled materials. Get started. Lace up and hit the road. Lightweight, Fast Construction for Coolness Mesh across the upper is lightweight and breathable. Based on feedback from runners, mesh is positioned in key areas around the instep to keep you cool where you need it. Laced, Supportive Design A strap across the midfoot provides stability. Thanks to the tape that comes together with the laces, the tighter you tie the laces, the better a structure you will have that will fix your foot.
