Our Take 

The Glycerin GTS 20 is a perfect blend of cushioning meeting support for those runners who enjoy a soft ride but might need a bit more structure.  With all the same changes as the regular Glycerin, the GTS adds their GuideRail® support technology to keep excess movement from foot to knee in check.  Other changes this season include the midsole going to Brooks’ 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.
