Good to know

  • The Adidas Speedfactory AM4NYC was designed in collaboration with running enthusiasts from New York. The suggestions and requests of many individuals were taken into account when they made the design of this Adidas running shoe.
  • The upper unit features a knitted textile, strands of thin overlays, a slip-on design, and flat laces. These elements work in tandem to secure the foot and keep it in place. An NFC chip on the instep allows the wearer to connect to the Adidas fitness app.
  • A full-length cushioning unit carries the foot as it goes through the gait cycle. It also receives the impact shock from the foot-strike and converts the force generated by that action to kinetic energy for the toe-off. A rubber exterior acts as a shield against wear and tear.

Standard measurements were used in the making of the Adidas Speedfactory AM4NYC, though it is highly encouraged to try out the shoe first to get a relaxed in-shoe experience. The available width is D – Medium, which is specific to men.

The semi-curved shape of the last and the slip-on design of the upper accommodates the natural curve of the human foot.

A rubber layer serves as the outsole unit of the Adidas Speedfactory AM4NYC. Its purpose is to protect the rest of the platform from the abrasive nature of the surfaces. It is also responsible for traction. Superficial gripping nodes heighten surface control while shallow grooves encourage flexibility.

Just like the popular Adidas Ultra Boost Uncaged, the midsole unit of the Adidas Speedfactory AM4NYC features the Boost™ cushioning foam, a full-length compound that’s made from the amalgamation of thousands of thermoplastic polyurethane pellets. It aims to mitigate the impact forces that are brought about by the foot-strike, then charge up the forefoot lift with kinetic energy.

The SPEEDFACTORY floating Torsion bar is located in the midfoot section. This plastic add-on supports the tendons and muscles of the underfoot, keeping them engaged and enabled to move. It also prevents the foam from sagging or wearing down quickly.

A knitted upper offers a form-fitting wrap. It also permits air to enter the foot-chamber, thus maintaining ventilation and dryness.

The SPEEDFACTORY patch reinforcement involves a set of thin overlays that bolster the structural integrity of the façade. These strips of synthetic material also help in providing a secure fit.

This running shoe has a slip-on design, which means that the wearer can slip the foot into the interior space with ease. It also evokes a smooth and seamless feeling that’s reminiscent of wearing socks or other slip-on footwear.

Flat shoelaces are present, and they help in adjusting the fit. They connect directly to the edges of the patch system.

An NFC chip is placed on the instep. This technology allows activity tracking via the Adidas app.

The heel section of the collar has a protruding tip to help the runner when it comes to wearing and removing the Adidas Speedfactory AM4NYC.
