George ★★★★★ Oct 22, 2026

The 4-inch inseam is perfect—not too short, not too long. I wore them for a tough leg day and they stayed put without riding up. Great fit for sweaty sessions.

Benjamin ★★★★★ Oct 20, 2026

The 4-inch inseam hits right above my knee, so I never have to worry about riding up during squats. The waistband stays put even when I’m sprinting on the treadmill. Exactly what I needed for hot gym sessions.

Charlotte ★★★★★ Oct 19, 2026

These are my new go-to shorts for leg day and cardio. The 4-inch inseam stays put during squats and doesn’t ride up, and the black color hides sweat well.
