What the AI looks for in Boys' Running Shorts

Waistband
Elastic waist plus an internal drawcord Kids' waists vary widely within a size. The drawcord stops shorts sliding down mid-stride.
Liner
Decide on lined, unlined with separate compression, or unlined over regular underwear Unlined shorts over cotton underwear are the main source of chafing on longer runs.
Length
Mid-thigh to just above the knee, with no fabric past the knee Long, baggy basketball-style shorts rub and catch the knee on every stride.
Fabric weight
Lightweight woven or knit polyester Heavy fleece or cotton shorts soak up sweat and sag.
