Our verdict
MIER offers well-featured running shorts, tops and accessories at budget-friendly prices, with most best-selling shorts in the $28–$38 range. Thoughtful details such as phone pockets, zip pockets and reflective trims, a broad size range and free 30-day returns make it an easy brand to try. Shipping can be slower outside the US, and the brand shares little about its history, but for everyday runners MIER is very good value.
