  • The Speedfactory AM4LDN is an Adidas running shoe that’s made using the inputs of runners from London. The ideas gathered from the people are combined, and the result of that collaboration is the product that comes out of the Speedfactory facility in Germany, an Adidas workshop that’s responsible for making the final product.
  • A knitted textile is used for the upper unit of this athletic apparel. It doesn’t have a tongue unit; instead, it features a one-piece design to deliver a seamless and irritation-free coverage. Discreet eyelets maintain the smooth scheme of the façade, and they’re supported by thin and assistive overlays.
  • The ever-famous boost™ foam runs the full length of the Adidas Speedfactory AM4LDN. It is responsible for providing a springy underfoot experience. A floating Torsion bar supports the underfoot and keeps the ride steady.

The Adidas Speedfactory AM4LDN has a standard running shoe length. It allows the runner to get a pair in their regular size. The width profile of this model is medium. It’s designed to fit the foot-dimensions of men.

A rubber compound serves as the outsole layer of the Adidas Speedfactory AM4LDN. It has a flexible nature. It also has a stretch-web design, which means that it resembles a grid, with focused nodes, connecting strands, and grooves. Traction, abrasion protection, and freedom of motion are the hallmarks of this structure.

Just like the popular Adidas Ultra Boost Uncaged, the midsole unit of the Speedfactory AM4LDN makes use of the Boost™ foam. This compound is made of TPU pellets that have been molded together to create a single platform. Its purpose is to cushion the foot, attenuate impact shock, and provide an energized toe-off.

A sock liner is placed above the main cushioning material. It adds a bit more support for the underfoot. It can be removed or replaced with a custom insert of the wearer’s choosing.

A knitted textile makes up the external part of the Adidas Speedfactory AM4LDN’s upper. It offers a form-fitting fit that doesn’t restrict movement.

A one-piece design removes the traditional shoe-structure of having a separate tongue unit. The instep and the rest of the cover system are of one layout, thus aiming for a consistent and coherent foot-wrap.

There is a traditional lacing system, but it’s inconspicuous in form and placement. The laces are thin, and they don’t intrude the one-piece look of the façade. Slits on the textile upper make up the eyelets, but they’re bolstered by synthetic overlays that extend to the lower midfoot and heel.

An external heel counter made of stretched textile holds the rear of the foot and prevents it from wobbling or exiting the foot-chamber accidentally.

The interior chamber is padded, and the sleeve is made of a smooth textile. Both these elements help in hugging the foot and keeping it safe from irritation.
