"I run the 60m, 100m, 4x100 and I set my pb in all with these also I won junior olympics gold with these" via Nike
"I run the 100, 200, and 400. I am also a horizontal jumper (long and triple), and I love these spikes. I find them to be quite comfortable and very durable as well. I order a new pair each season. Although they're not designed for jumping, they work really well, especially since I rarely have time to change into a different pair of shoes between my jumping and running events. I've tried other spikes and have always stuck with this pair. I use them for competing and practice the day before a meet so I use them fairly often." via Nike
"I’m a sprinter in the 4x100 relay and the 200 meter dash in high school.The curved lacing design is very helpful while running the curve of the 200, by the end of the season I cut off more than 1.5 seconds in the 200! The fit is snug, as all spikes should be. I recommend to anyone willing to run faster and look good while doing it, big thanks to Nike on this great track shoe" via Nike
