The Ultra BOOST is designed with a seamless mesh that truly hugs the foot. I wasn't sure I liked this (more on that later), but I've grown to love the secure feel these shoes provide; and given the nature of the weave, they're extremely breathable.

Manufacturing focused: the Boost midsole material is licensed by adidas from the BASF company. That means a licensing fee that makes the material more costly to use than if it had been developed in house (like Nike's React foam was).

Firstly, the creamy Ultraboost Made To Be Remade is a fully recyclable shoe and comes with a QR code on the tongue that you can scan with your phone to arrange for them to be collected. The shoes will then be taken to an Adidas store and broken down and upcycled to create a brand new pair.

The lifespan of Adidas Ultra Boost shoes can vary depending on several factors such as usage frequency, maintenance, and terrain. Typically, with regular use, the shoes can last up to 6 to 8 months before needing a replacement.
