    The Ultra Boost ATR held up really well.I didn't slip on anything, I felt really surefooted.

  • 88 / 100 | Kikay Runner | | Level 3 expert

    I’m accident-prone and can trip over my own feet, but the shoes kept me feeling secure and sure-footed. With all the grit on the road as well, I half-expected to take some archeological debris past the finish line, but not one stone got into the shoe thanks to the high ankle.

    The Adidas Ultraboost [X] ATR is an ideal pair for neutral runners who love to run outdoors. The comfort of the Primeknit material is great and the water-repelling feature is quite decent.

  • Adidas collaborates with fashion designer, Stella McCartney, to create a new iteration of the Ultraboost X All Terrain shoe. This model bears the name of the famous road-and-trail footwear, yet it features a fashion-forward design that allows it to lean more towards being worn on the streets.
  • The façade is made up of recycled polyester yarn. It’s sturdy, flexible, and it brings an environment-friendly quality. TPU overlays cover the front, the heel, and the lower midfoot section.
  • Cushioning is provided by the Boost foam. This full-length material is meant to encourage a springy underfoot experience. Continental™ rubber offers protection against the abrasive nature of the surfaces, be it road or trail.

The Adidas Ultraboost X All Terrain was configured using the standard measurements. Lengthwise, it’s designed to accommodate expectations. But it is also recommended to try on the shoe first before making a purchase. When it comes to width, the only option is B – Medium as this shoe is exclusively made for women.

The outsole unit of the Adidas Ultraboost X All Terrain is made of Continental™ rubber, which is similarly used in car tires. Runners can expect heightened traction and surface control with this material.

The Stretchweb design is comprised of traction nodes that are connected by depressed rubbed nodes. This configuration allows the external pad to bend and accommodate the natural movement capacity of the foot.

An All-Terrain build makes this shoe versatile. The outsole has mildly prominent lugs, but their ends are flat, permitting traversal over even surfaces.

The cushioning platform is composed of Boost™, which is a full-length unit made up of thousands of fused thermoplastic polyurethane pellets. The job of this compound is to provide springy toe-offs and attenuated foot-landings.

Primeknit serves as the upper unit of the Adidas Ultraboost X All Terrain. It is made of recycled polyester yarn. The environment-friendly implications may attract conservative purchasers and enthusiasts of sustainable materials.

Thermoplastic polyurethane (TPU) prints grace the front, the heel, and the midfoot. These wraparound add-ons are arranged in such a way that the foot is protected from bumps and scratches while also being held in place.

A sock-like construction of the façade permits the feeling of merely wearing a sock. The stretchy, one-piece collar embraces the lower leg and the ankles securely.

An external counter with the ‘Adidas’ wording secures the back of the foot, preventing it from wobbling or destabilizing.

A pull tab is placed on the rear part of the collar. This fabric is helpful when it comes to wearing and removing the Adidas Ultraboost X All Terrain.
