Updates to Under Armour Spine Venom 2

  • The 2nd version of the Spine Venom from Under Armour doesn’t look any different from its original version. But this iteration has a more curved shape that further follows the natural curvature of the human foot. Runners can acclimate well when actually wearing it.
  • The upper unit makes use of a breathable mesh material that also has a foam underneath it. It delivers a secure and comfortable coverage that’s also well-ventilated.
  • The collar and underfoot insole are made from a material that molds into the shape of the wearer’s foot. As the runner continues to wear this shoe, its platform and collar immediately shapes itself to fully provide support to the waves and curves of the specific foot.
  • A foam-based chassis in the mid-sole is a lightweight support system that also gives flexibility. The support that’s given by this unit is given to areas that need it the most.
  • The outsole features a rubber material that’s placed in areas that are prone to wear and abrasion. It’s a lightweight inclusion to this shoe, so it doesn’t weigh the runner down, but it does deliver surface traction and protection.

Under Armour Spine Venom 2 size and fit

The Under Armour Spine Venom 2 is true to its size. It is available in a wide range of sizes that adhere to the norm. Its curved shape allows the foot to acclimate well when wearing it. The heel, mid-foot and forefoot sections have a medium width, so runners with medium foot-dimensions are the ones who’ll find it fits well.


The outsole unit of this running shoe makes use of a solid rubber compound. It’s placed in specific sections of the outsole where wear and tear are most noticed. They deliver durable protection against the abrasive nature of the roads, while also giving traction over the roads.

Flexibility is afforded by the outsole. It works well with the mid-sole unit in delivering natural freedom of motion, so runners can stay engaged throughout the running cycle.


The UA Spine™ chassis is a foam technology that makes up part of the mid-sole unit. It actually looks like part of the human spine and its purpose is pretty similar. It delivers structured support to the foot. From the heel to the forefoot area, the chassis is able to give underfoot support because it functions through the gait cycle.

The Micro G® foam is placed above the chassis of the Under Armour Spine Venom 2. It’s made from a durable yet responsive material. It has bounce-back mechanics, so the foot can experience a bit of springiness to every step. It also gives back impact energy to the runner to make each step more empowering. This midsole foam is also used in other Under Armour running shoes, like the Micro G Assert 7


The upper unit of this running shoe uses a breathable mesh that continually lets air into the shoe to keep the foot cool and dry. It has a cushioned foam underneath it to give additional support to the foot. Now, the upper wrap feels snug yet comfortable.

The overlay system used for this model was fused onto the upper. They maintain the structural integrity of the fabrics and they make sure to hug the foot well through active participation with the lacing system.

A TPU Heel Counter locks the rear of the foot in place, therefore preventing any accidental shoe removals. It’s not too rigid, so it doesn’t render the unit irritating or uncomfortable.

The molded 4D Foam® Sock Liner and collar conforms to the shape of the wearer’s foot. By doing so, the entirety of the underfoot is subjected to a soft and supportive platform. It also effectively locks the foot in place, thus preventing any slippage.
