Your race: 3K to 10K. The Zoom Streak LT 4 is a true racing flat for chasing competitive times on the road or track, while its lugged sole will give you traction over grass, groomed trails, or a cross country course. At just 5 ounces in a men’s size 9, these are the lightest Nike shoes—and that’s saying something on a list where the average is barely over 7 ounces. If you’re an aspiring road warrior or NXN finalist, the Zoom Streak LT 4 deserves a spot in your closet next to your track spikes.
