Good to know

  • The Adidas Ultraboost X 3D is considered one of the most successful Adidas running shoes designed for women. This road running shoe is created for users who love to run in style and comfort. 
  • Like the Adidas Ultraboost X, the Adidas Ultraboost X 3D features a 10 mm drop. It also incorporates the  Boost™ cushioning technology, flexible Stretchweb outsole, and Primeknit upper. The running shoe is also manufactured with yarn created in collaboration with Parley for the Oceans.
  • Although the technologies used have not really changed when compared to other Ultraboost Parley running shoes, the Ultraboost X 3D now uses the slip-on construction. It allows the user to put on the shoe easily without a lot of ties, buttons, or fasteners.

The Ultraboost X 3D is manufactured using the standard shoe measurement to accommodate the usual choices of consumers when it comes to size. However, it is important to fit the shoe first or utilize the general feedback about sizing to ensure a perfect fit. 

The shoe includes a compression fit adaptive arch that is designed to conform to the shape of the woman’s foot, providing a more comfortable in-shoe feel throughout the running session.

The Continental™ Rubber comprises the outsole of the Adidas Ultraboost X 3D. This rubber material is the same technology that is used for car tires. It makes the shoe more durable and provides better grip compared to other rubber outsoles. 

Like the Adidas Ultraboost and Ultraboost 19, the pattern used on this lightweight running shoe’s outsole is called StretchWeb. This component makes the outsole more flexible and allows the shoe to move and bend naturally with the foot. 

The Boost™ cushioning is integrated into the midsole section of the shoe. Boost™ is Adidas’s most innovative midsole cushioning technology that is made up of a material called thermoplastic polyurethane (TPU). While running, the TPU material compresses and instantly bounces back to its original shape to provide better shock absorption. 

The compression fit adaptive arch molds to the shape of the woman’s foot, providing a more comfortable compression fit while walking or running. 

The Adidas Ultraboost X 3D utilizes the slip-on style, allowing the shoe to be easily removed but remains snug when worn. The dual supportive elastic bands that are placed across the vamp helps provide a snugger in-shoe feel. 

The upper presents the Primeknit technology that offers a sock-like fit and breathable comfort. It keeps the shoe well ventilated, keeping the foot cool and dry for an extended period. 

The Parley Ocean Plastic™ is also incorporated in the upper unit. This component is made from upcycled waste intercepted from the coastal communities before reaching the ocean. It is used to replace virgin plastic in the manufacturing of Adidas X Parley products.
