Good to know

  • The 2nd version of the Under Armour Charge RC may initially not look any different from its predecessor when initially observed, but it actually has a more spacious mid-foot to accommodate a variety of foot types. It also uses a more articulated material in the upper to allow the foot to move more naturally.
  • The geometry of the sole unit was deliberately designed to let the foot have constant contact with the ground. It’s a helpful way to get surface feedback to keep the runner balanced and alert about the surfaces.
  • The mid-sole features some very efficient technologies that assist the runner in getting protection from shock, as well as energy for a more efficient stride. Landings are also well-cushioned because of a responsive foam system that carries the foot well throughout the gait cycle.
  • The mid-foot section of the Under Armour Charge RC 2 has a medial bumper, which prevents the rolling in of the foot, thus resulting in a more neutral stance when wearing it.
  • Durable rubber is placed on certain areas of the outsole where wear and tear are most commonly observed. It delivers protection, as well as traction when doing turns, swerves and breaks. The material is lightweight, so it doesn’t affect the overall weight of the shoe.

The Under Armour Charge RC 2 is slightly bigger in size than the standard. It is recommended for runners to get ½ size smaller to be able to get the right one. It has a medium width when it comes to its heel, mid-foot and forefoot areas. Its semi-curved shape allows it to accommodate the natural shape of the human foot.

The Light Speed Grip is a compound that is found on the outsole unit of this running shoe. Strategically placed in areas that are at risk from wear, it protects the sole unit and delivers responsible traction over the roads.

The forefoot area has flex grooves that allow the runner to perform more naturally, particularly during the toe-off phase. It doesn’t restrict the pliability of the mid-sole and the upper unit.

The Micro G® is a mid-sole foam that delivers cushioning throughout the stride. Because it’s a full-length foam, it is able to protect the foot from impact during heel strike and then make each toe-off more explosive. The Micro G is as popular as the Gel cushioning found in the Gel Kayano 25 running shoe.

A Medial Bumper that’s made from TPU cradles the arch and carries it well when standing and even when running. It prevents the medial side of the foot from rolling over and then shifts the stance of the runner to assume a more neutral one.

The 4D Foam® is a foam unit on top of the main mid-sole layer. It’s made from highly responsive materials, that’s why when the runner steps on it, it molds itself to assume the exact shape of the underside of the foot. Such a design adds more support to the contours of the foot and even prevents any slippage from happening.

The articulated upper flex capability of the fabrics makes it very responsive to the movements of the foot. It mimics the bending of the foot when it goes through the gait cycle, so it gives more freedom for natural movement.

The HeatGear® fabric is able to wick off moisture and keep the upper unit dry. It provides a cool and well-ventilated environment for the foot. Sweat doesn’t get absorbed in it, thus preventing odor.

The MPZ® technology is the tongue padding that protects the foot from impact and discomfort throughout any activity. It’s durable, lightweight and firm, so pressure points won’t make the skin irritated.

An External Heel Counter enhances the fit of the shoe. It locks the rear of the foot in place and prevents accidental shoe removals.
