Running shorts look simple, but the wrong pair can cause chafing, distraction and discomfort long before you reach the finish line. Here is how to pick a pair that works for your body and your training.
Consider Your Distance
For short, fast runs, lightweight split-leg shorts with a short inseam (3 to 5 inches) allow maximum freedom of movement. For long runs, a slightly longer inseam, around 5 to 7 inches, can reduce thigh rubbing and give you room for pockets to carry gels, keys or a phone.
Lined or Unlined?
Built-in liners remove the need for separate underwear and cut down on friction. Some runners prefer unlined shorts worn over compression tights or briefs. Try both options on a few short runs to see what feels best.
Waistband and Fit
A good waistband should stay put without digging in. Look for a flat, wide band with a drawcord, or an elastic band with a silicone grip. Test the fit by jumping and jogging in place; if the shorts ride up or slide down, try another size or cut.
Fabric Matters
Choose lightweight, quick-drying synthetic blends with some stretch. Mesh panels and perforations help with airflow in hot weather, while flat seams reduce irritation on long runs.
Pockets and Storage
- Back zip pockets keep small essentials secure.
- Side pockets are handy for phones, but make sure they do not bounce.
- Reflective details add visibility for early-morning or evening runs.
The Bottom Line
The best running shorts are the ones you forget you are wearing. Match the inseam, liner and fabric to your usual distance and climate, and test them before race day.
