He doesn’t provide any sourcing, but an Instagram user with the handle @brandonlaw, who is clearly an avid runner and shoe geek, posted the following comparison between the Superblast 2 and soon-to-be-released Superblast 3 (note that he’s posted pre-release imagery and info in the past that have proven to be correct).

The move to FF Leap + the 1.5mm increase in height at the forefoot & heel + a slight reduction in weight have me pretty excited about the 3. But I’m surprised that info and images are already leaking, given that, as far as I’ve read, the 3 isn’t due to hit retail until March 2026.
