Review summary
Written by Augur from the 23 reviews analyzed
The Brooks Glycerin Flex is a road running shoe particularly appreciated for its regular use. It stands out for its immediate step-in comfort and a flexible sole that provides excellent responsiveness as well as highly effective cushioning with every stride.… The main point of concern is the design of its outsole, which tends to catch small pebbles during runs.
