Our Take 

For twenty seasons the Brooks Glycerin has been that reliable, cushioned, great fitting everyday trainer that people have come to love.  This season we see a big overhaul from top to bottom and they are all changes we love.  The updated midsole is now using nitrogen-infused DNA Loft V3 cushioning.  Nitrogen infusion allows for max cushion creating Brooks’ softest midsole while maintaining responsiveness on push-off.  It also allows for more durability in the midsole. The redesigned outsole provides a smoother transition from heel to toe.  The widened midfoot and outsole provides a more stable ride and offers an amped up cushion experience (the GTS provides an even wider midfoot for additional stability) and the new engineered air mesh offers more durability and breathability.
