The Sequins Are Load Bearing
Pro runners are bedazzling their own race kits by hand. The extra grams are apparently worth it.

Yes, it weighs more. The argument is that confidence weighs something too, and that showing up looking like a disco ball changes how the next 400 meters feel. Hard to test in a lab. Very easy to see from the stands.
Medals, PRs, confidence. The crystals are doing work.
