The Brooks Glycerin line has been a staple for runners looking for comfort and cushioning over easy miles for over two decades. The Glycerin 20 saw some of the biggest developments seen in the line for quite some time, developing the shoe into a more versatile cushioned daily shoe than one designed purely for easy days.

Although the Triumph 20 saw a number of updates over its predecessor, the 21’s changes are largely made across the upper. The new design gets a revamped flat knit material to improve fit, as well as provide breathability, along with a modified lacing system for better lockdown.

The shoe features the same PWRRUN+ cushioning in the midsole and sockliner – an impressively balanced foam that manages to feel soft while still providing a good level of energy return, and there’s a generous level of outsole rubber to protect that foam and deliver a high level of grip across varied road conditions.

Tom, Kieran and Nick have been testing the shoes out to see which is worth spending your money on.
