FAQs
Inseam length for running?
3-5" for racing and speed. 7" for everyday training. 9" for casual or modesty preference. Trail running often 5-7". Marathon training 7-9".
Liner or no liner?
Most running shorts have built-in mesh briefs. Compression liners reduce chafing. No-liner shorts go over your own briefs or compression shorts.
