Brooks has succeeded as a running brand by focusing solely on running. This attention to detail is evident in the new Glycerin 20, as the familiar look is updated by new materials, that results in improved performance. The upper features an updated design which provides comfort and ventilation, while maintaining its stylish look.
The midsole debuts a new foaming process using supercritical nitrogen, which bolsters the ride, now a little bouncier, while delivering a more durable material. While it has a little different feel than Brooks’ , the tradeoffs in resciliency and durability are worth the adjustment
as it has a bouncier and more resilient ride.

The bottom line is that the Deluxe ride has become Deluxer, maybe even Deluxerer
