Made of TPU-reinforced performance mesh with engineered synthetic leather overlays, the Under Armour men's Proto Speed IV shoe maximizes ventilation and support while minimizing weight. The shoe is made using Under Armour's Directional Cushioning Engineering (DCE) system, an integrated technology that blends several comfort and stabilization technologies into a single design.

The Proto Speed IV is made of TPU-reinforced mesh with synthetic leather overlays. |
DCE starts with ArmourLastic technology, which absorbs shock at critical impact zones in the heel and forefoot to provide maximum protection. The shoe's ArmourBound design, meanwhile, keeps your foot cushioned and comfortable while on the move. DCE completes the circle with its ArmourGuide technology, which encourages efficient foot-strike guidance from impact to propulsion. Combined, the technologies keep the foot in constant contact throughout the gait cycle, creating more stability and mid-foot support.
Structure-wise, the shoe employs Cartilage Smooth Transition technology, the connective tissue of Under Armour's performance footwear. Cartilage Smooth Transition materials have elastic, protective, and stabilizing properties that replicate the function of cartilage in the human body. This helps the shoe--which is built with a minimum of 6mm internal thickness--absorb the initial impact and reduce the shearing forces present when running. The shoe's structure also includes a ventilated internal Footsleeve, which is engineered to hug the foot and eliminate sliding and extra bulk.
Other features include a HeatGear-lined upper that pulls moisture away from the foot to keep you cool and dry; a Total Contact non-marking rubber outsole that provides later stability; clear rubber, multidirectional traction pods in the heel and forefoot for secure traction on varied surfaces; anti-odor technology that prevents the growth of odor-causing microbes; and strategic vent zones built into key points where the body dumps heat.
About Under Armour
It started with a simple plan: Make a superior T-shirt, a shirt that provided compression and wicked perspiration off your skin rather than absorbing it, and that worked with your body to regulate temperature and enhance performance. The plan evolved into a full-fledged commitment to producing performance apparel engineered to keep athletes cool, dry, and light throughout the course of a game, practice, or workout.
