That new foam is now a proprietary Norda x Arnitel thermoplastic polyester elastomer blend that aims to deliver 30 percent more rebound than the original 001. It weighs 10 percent less and still delivers that signature durability that lasts beyond 1,000 kilometers (621 miles).
When it comes to running shoe technology, Brooks is normally a follower rather than a trendsetter. Nike, Puma, New Balance, Saucony and even Skechers started using supercritical midsole foams years before Brooks joined in on the fun. Brooks' first innovative shoe was the Aurora-BL concept trainer in 2021 that used DNA Loft V3 (supercritical EVA). The Aurora-BL had a fun, energetic ride unlike any other Brooks trainer. It's still my favourite Brooks running shoe to date.
