Adidas Pureboost 21: The Boost is not done yet 

Although we're already seeing the Lightstrike foam making its way into the Adidas running shoes, in the 21st iteration of the Pureboost, Boost tech still reigns king. What does this mean? Comfort and responsiveness are paramount. 

Even better, it's light as ever. Dragging sensation? There's none of that in the Adidas Pureboost 21. 

Who and what is it for? 

The Pureboost 21 is designed for neutral runners looking for a road shoe that prioritizes comfort and can handle: 

  • easy runs
  • jogs
  • walks
  • gym training 

Pureboost 21 vs. predecessors: What's changed? 

  • More support: It has a wider base to keep your steps steady and stable. 
  • Better ground feel: This is because of the lessened Boost foam, allowing better navigation underfoot. 
  • Less heel reinforcements: It's both a good and a bad thing. Good because it's less harsh to the heel, and bad because it means there's less support. And true enough, there have been reports of heel slips and movements. 

A step toward sustainability 

Made with Primeblue materials, the Adidas Pureboost 21 takes part in the brand's initiative to end plastic waste by 2024. 50% of its upper is made with recycled materials.
