Good to know

  • Under Armour presents the new SpeedForm Slingshot, the newest in its running shoe line-up. This shoe training shoe uses a 3D knit upper. The idea in the concept of this shoe is to provide one that has a lively and springy upper just like how its midsole feel. The Speedform Slingshot is designed with 3 dimensionally knitted upper with 3 zones of different compression.
  • The lateral side of the upper is tight and springy, the medial arch area is designed with the tightest compression, while on the forefoot, a slightly loose compression is used. This design allows the foot, especially the toes to spread during stride while it keeps the mid-foot area snug and fit.
  • Part of the new construction of the upper is the Dynema, a super strong thread or yarn used to wrap the forefoot area. With this design, the toe are free to spread and move but stayed secure for better fit.
  • This new shoe design has midsole that consist of two types of foam being sandwiched in the Y-shaped plate. It allows the foot to flexes and spring back in each stride, just like how a slingshot works.

Locked down fit, hug in the heel, and snug fit from mid-foot to toes, the SpeedForm Slingshot has a fit and sizing suitable for standard size foot. The 3D knitted upper in three dimensional zones is combined with the Dyneema yarn to construct the upper not just for a snug fit feel, but also to achieve the slingshot spring. The SpeedForm Slingshot is available in standard running shoe length and width.

The outsole of this shoe has an anatomical design for a more natural fit and performance. The rubber placed on the outsole delivers high quality traction and durability at the same time at less the weight. With this design, the shoe is responsive and efficient for quality performance. The outsole of this shoe is as durable as the outsole of the Slingshot 2 running shoe.

The midsole of this shoe are designed with the Micro G foam and Softer Charged foam. In between these two foams is the TPU Y-shaped plastic plate, giving the shoe a springy and flexible feel with a supply of ample stability for a fast ride.

The Under Armour creates a new upper design. Its sleek look is attractive, as well as its construction. The seamless wrap of 3D knitted materials combined with the strongest form of fiber for shoes, the Dyneema, this shoe is just an innovation for optimal fit and durability. The sock-like tongue is like a burrito wrap that provides precise fit and guidance, allowing the foot to move like compression spring empowering each stride.
