  • The Adidas Speedfactory AM4LA is a road shoe that’s designed for city running. It’s also configured for neutral pronators. An uncluttered façade graces this product, and it’s highlighted by a lightweight and breathable build.
  • A knitted textile serves as the upper unit, and it’s made using recycled plastic. Environmentalists may find such an arrangement to be appealing. Since this shoe was made in Germany’s SPEEDFACTORY facility, it’s adorned with a floating torsion bar, a patch-based reinforcement system on the upper, and a glue-free construction.
  • The midsole unit makes use of the boost™ foam. It carries the foot and energizes it when taking each step. A grid of rubber covers the cushioning platform, preventing it from succumbing to surface abrasion and the potentially damaging effects of continued use.

The Adidas Speedfactory AM4LA features standard sizes. It is still recommended to try out the shoe first before making a purchase; doing so would yield a more relaxed in-shoe experience. The width profile of this running shoe is D – Medium. It is only available for men.

The Adidas Speedfactory AM4LA features a rubber outsole that has a grid layout. Non-prominent traction nodes ensure surface control while shallow indentations provide flexibility.

Same as that in popular Adidas Ultra Boost, cushioning in Speedfactory AM4LA is provided by the full-length boost™ foam. This compound was born from the amalgamation of thousands of thermoplastic polyurethane pellets. Its purpose is to give a springy underfoot experience. It also attenuates impact during the landing phase of the gait cycle.

The Speedfactory floating torsion bar is a reinforcing plastic in the midfoot section. It bolsters the structure of the combined pellets, preventing it from sagging quickly. It also supports the muscles and tendons of the underfoot.

A knit-material serves as the outer section of the Adidas Speedfactory AM4LA’s upper. It’s created using a unique yarn by Parley for the Oceans. The Parley Ocean Plastic™ is an uncommon fiber that’s made from recycled materials. The final product resembles a textile’s look and texture.

The climalite fabric is used for the interior sleeve of this running shoe. It is soft, and it has moisture-wicking properties to maintain a dry environment for the foot.

The Speedfactory patch reinforcement scheme offers a lightweight wrap. Pieces of this overlay system reinforce the heel, the midfoot, and the eyelets of the lacing system.
