"Since it's just way too hot to run in long tights right now (back-of-the-knee sweat can get itchy quickly in leggings), I researched Old Navy's running shorts, focusing first on length and fit, and I found the Old Navy Dolphin-Hem Run Shorts ($15). When they arrived I immediately put them on for a 20-minute HIIT run (read: lots of sprints). If there's one surefire way to test whether or not shorts are going to bunch in your crotch it's by opening up your stride and sprinting. During the run I didn't fiddle with the shorts once. The waistband remained snug without digging into my skin. I loved them — the shorts felt more like silk pajama shorts than workout gear, and the inner lining was lightweight." — RB
