After a hugely successful overhaul of the Nimbus with last year's version 25, this year's 26 appears to build off that success with a few smaller improvements...

-The midsole is comprised of FF BLAST ECO PLUS cushioning, which is Asics' softest cushioning yet AND is made from ~20% bio-based content using renewable resources.
-A new outsole called HYBRID ASICSGRIP delivers reliable grip with a soft feel for improved traction.
