The materials and technologies that are used for this model are all of high quality and they work in tandem with the wearer to ensure quality service and performance.
  • The upper unit utilizes a high quality mesh material that doesn’t have a substantial weight. It wraps around the foot in a snug yet secure manner, but it doesn’t make the interior stiff or stifling. Air is allowed to seamlessly enter the shoe to keep the foot cool and dry. Foam placed below the mesh provide additional comfort to the shape of the foot, while overlays assist the fabrics in keeping it in place.
  • The underfoot cushioning system of the Under Armour Micro G Assert 6 uses a full-length foam technology that is very responsive to the purpose and reason for running. It cushions the foot during impact and assists it in taking off. Its plush nature won’t let the wearer feel an uncomfortable firmness to the platform.
  • A full-length rubber material is used in the outsole of this running shoe. It shields the rest of the sole unit from wear and tear. It’s also the part that’s responsible for the traction the runner gets when tackling the roads. Flex grooves allow the platform to move naturally with the motions of the foot.

The Micro G Assert 6 runs a bit bigger than what is common, so it is recommended for runners to get 1 size up in order to get the right fit that’ll accommodate their comfort. The available width is medium, making it agreeable to those who have medium sized feet. Its semi-curved shape welcomes the natural curve of the human foot.

A non-marking rubber material is used in the outsole unit of this running shoe. It is durable and lightweight. It is responsible for protecting the mid-sole from the abrasive nature of the asphalt, keeping it intact and free from damage. Traction is also received from this unit and it is reliable.

Flex grooves allow the platform to become more flexible. Having such a design removes the stiffness of the sole unit. It also gives way to the natural movement of the foot.

The Micro G® is a full-length foam that provides the cushioning needed to keep the foot comfortable throughout the running session. It supports the natural stride of the wearer and makes each toe-off more explosive because of its springy nature. This midsole foam is also used in the Micro G Assert 7 and other popular shoes from Under Armour.

A sock liner made from Ethylene vinyl acetate is placed above the main mid-sole unit. It offers additional cushioning and support to the foot.

A lightweight mesh material is used in the upper unit of the Under Armour Micro G Assert 6. It moves along with the foot while also keeping it comfortable. It allows air to ventilate the interior, essentially keeping the foot dry and cool for longer running times.

A supportive foam lines the interior of this shoe. It doesn’t have a heavy weight and it doesn’t make the interior stiff. What it does is it cushions the dimensions of the foot.

Overlays made from durable leather lock the foot in place and gives structure to the upper. Connected to the lacing system, these overlays adapt to the tightening or loosening of the shoelaces, basically making the fit more customizable.
