Outsole
Outsole

Outsole

Under Armour made use of a solid rubber compound when designing the Spine Venom 2. The design and structure of the outsole are the same as the old version of the Spine. This rubber material is placed in areas of high wear and tear, improving the durability of the outsole. In addition to durability, the rubber outsole gives the runner traction on the roads. Another key feature of the Under Armour Spine Venom 2 outsole is flexibility. Under Armour designed the outsole of the Spine Venom 2 to work with the midsole unit to give runners natural foot movement. Runners are able to stay engaged throughout the running stride.
Midsole
Midsole

Midsole

The Under Armour Spine Venom 2 utilizes two types of foam technology throughout the midsole unit. The first foam technology is the UA Spine chassis, which looks and acts like the human spine. The purpose of the UA Spine chassis is to give the wearer underfoot structured support from the heel to the forefoot area. Micro G foam is then placed above the UA Spine chassis. This foam technology is a durable and very responsive material. Runners experience a springiness or bounce-back during each step. The Micro G foam also uses energy produced from impact to make the runner feel stronger during each stride. This foam material gives runners a cushioned landing and is lighter and more streamlined than traditional foams. Wearers commented on the wonderful comfort provided by this Micro G foam, saying it was just enough foam without increasing the weight of the shoe.
Upper

Upper

The Under Armour Spine Venom 2 keeps your feet cool, dry and comfortable with its breathable mesh upper. The upper unit has a cushioned foam material underneath it for added security, comfortable foot coverage, and ventilation. This cushioned foam material gives the runner's foot additional support without making the shoe feel heavier. Under Armour added this MPZ padding to the upper, when compared to the original version of the Spine. The Under Armour Spine Venom 2 uses an overlay system that is fused onto the upper, rather than stitched to it. The wearer will experience a foot-hugging fit as the overlay system actively works with the lacing system. Some wearers commented that this shoe fit like a glove and they had difficulty getting it on. This running shoe features a TPU heel counter and underfoot insole that mold to the shape of the runner's foot. The insole is a molded 4D Foam Sock Liner. This material instantly shapes itself to support the way in which the runner's foot waves and curves. The heel collar keeps the rear of the foot locked in place, preventing the foot from slipping out. The heel collar is not very rigid so there is minimal irritation or feelings of discomfort during wear. Overall, the upper unit offers the runner a soft, supportive, secure and comfortable fit.
