FIT: Designed to be worn barefoot, the Minimus shoes provide a tight fit and snug slipper-like feel. Many of our customers order a half size larger, especially when they intend to wear socks.

CAUTION: This product should be introduced slowly into a running exercise routine. New Balance recommends limiting initial use to 10% of overall running workouts and very gradually increasing time and distance.
