Updates to Adidas Ultraboost X Parley

  • Largely unchanged from the original Ultraboost X, this new version was born from the collaboration between Adidas and Parley for the Oceans, a company that specializes in producing materials from recycled plastics. Yarn made from recycled materials is actually used for the upper unit. It mainly looks the same, but with an environmentally friendly twist.
  • A floating arch is designed to allow the whole upper fabric to encompass the foot, thus delivering a sure and secure fit.
  • The mid-sole unit of this running shoe utilizes the Boost technology, a high-quality foam material that’s made of thousands of amalgamated cushioning pellets. The full-length unit aims to cushion and protect the foot from impact shock when landing on the ground.

Adidas Ultraboost X Parley size and fit

The Adidas Ultraboost X Parley has a standard running shoe length. It accommodates the regular choices of runners in terms of size. The available width is medium. It only has a women’s specific design, so it caters to the natural shape of the woman’s foot.


The outsole unit of the Adidas Ultraboost X Parley makes use of Continental™ rubber, which is a brand that specializes in tire-treads. The material that’s used in this shoe is durable and efficient when it comes to offering surface control.

The Stretchweb design allows the platform to flex and move along with the natural motion of the wearer’s foot.


Boost is a full-length unit that’s made from the compaction of thousands of tiny cushioning pellets. It carries the foot responsibly and allows it to experience springy and well-cushioned steps throughout the running session.


The upper unit of the Adidas Ultraboost X Parley features the Primeknit. It’s a material that has the disposition of knitted cloth. It’s breathable and it securely wraps the foot in a non-irritating manner. The yarn that’s used here actually features the Parley Ocean Plastics™, which were removed from beaches and seaside homes before they ever reach the oceans.

Stitched-on overlays are added to the sides of the shoe. Connected to the lacing system, they help the upper in adjusting the fit to the preference of the wearer.

A floating arch is featured in this shoe. It essentially separates the mid-foot section of the upper from the main mid-sole unit, allowing the fabrics to encompass the arch of the foot.

An external heel cap holds the rear section of the foot in place and prevents it from exiting the shoe accidentally.

The garter-collar design provides the impression of merely wearing a sock. Also, it embraces the base of the lower leg, essentially preventing the foot from slipping off.

A pull tab in the heel area provides assistance when it comes to wearing and removing the shoe.
