This is the way Under Armour does running shoes: light, ventilated, and amazingly comfortable. The Micro G Assert 6 Running Shoe's upper is crafted from a lightweight, supportive foam underneath a soft layer of breathable mesh. Durable leather overlays increase stability and lock in the midfoot. An antimicrobial treatment applied to the footbed helps minimize the risk of odor-causing bacteria and infectious fungus. The full-length Micro G foam midsole offers thin, light, and super-responsive cushioning that supports the stride, turning cushioned landings into explosive takeoffs. Nonmarking rubber is strategically placed in high-impact zones of the outsole for greater durability and traction without excess weight. The lace-up front closure ensures a secure, personalized fit. Medium width. Imported.
