  • The Adidas Ultraboost 20 is a high-performance road running shoe updated with a stylish, modern look. It is packed with state-of-the-art technologies, helping the user run faster and farther.
  • This Adidas running shoe features a more flexible Primeknit upper that utilizes a new technique called Tailored Fiber Placement. This technique helps ensure a more accurate fit for all types of foot. The TPU midfoot cage and clip included in the upper have also been updated to provide extra support. 
  • The Ultraboost 20 still features the Boost™ midsole and Strechweb technology for a comfortable and responsive feel. 

Lying in the outsole is the Continental Stretchweb technology that delivers a larger contact area for better traction on various surfaces. This highly durable rubber material also offers reliable protection against sharp objects and small rocks. This technology is also featured in the Adidas Adizero Boston Boost 7 and Adidas Solar Glide ST.

The Adidas Ultraboost 20 utilizes the Boost™ technology, which provides excellent cushioning and incredible energy return. The Boost™ midsole cushioning is compost of tons of little capsules that are made of polyurethane. This component gives the runner back up to 55% of the energy exerted in every impact. It helps the user run faster and more effortless. 

The Torsion® system is also encapsulated within the midsole foam for an improved transition and propulsion. The Torsion® spring is positioned in the center of the lower portion of the shoe, connecting the front and back of the platform. The spring transfers the strength of the feet from one part to another. It allows an independent movement for maximum flexibility and added stability. 

The upper of the Adidas Ultraboost 20 uses the Primeknit technology for a breathable, sock-like fit. The knitted upper is made from recycled waste materials that are intercepted from coastal communities and beaches before they reach the oceans. The upper keeps the foot well ventilated and cool for an extended period. 

The Tailored Fibre Placement (TFP) technology utilized in the upper provides stitching across every single millimeter for targeted midfoot support and breathability. 

The TPU midfoot cage and clip are designed to deliver extra support while the 3D heel frame is added to securely hold the ankle in place while running. The traditional lacing system is also used for a customized fit. 

  • The 20th edition of the Adidas Ultraboost is created as a symbol of the partnership between Adidas and the International Space Station (ISS). The passion for innovation has brought these organizations together. Inspired by their desire to empower the athletes of the Earth, they will send the Adidas Ultraboost 20 into the space to push the limits of possibility.
