Adidas shorts sizes are accurate to typical ready-to-wear waist sizes across the industry. It’s always good to review their size chart (available on the Adidas website) to make sure you’re choosing shorts that will not be too loose or too tight at the waist. If the inseam length isn’t listed on the product description, keep in mind that Adidas shorts fall at typical lengths: between 3 and 4 inches for short shorts, 5 to 7 inches for mid-thigh, and 10 to 11 inches for longer shorts ending a couple of inches above the knee.
