FAQs
Are these shoes suitable for overpronation?
The Glycerin Flex is a neutral trainer designed for natural motion and does not feature the traditional structure found in motion-control or stability-specific shoes.
Can I use these for gym workouts?
While the cushioning is excellent for running, the high level of flexibility may make them less stable for heavy lifting or lateral-heavy gym training.
Does the nitrogen-infused midsole change over time?
Like all foam materials, it will compress with heavy usage, but the nitrogen-infused DNA Tuned technology is designed to maintain its responsiveness longer than standard EVA foams.
How do I know if the fit is correct?
You should have about a thumb's width of space between your longest toe and the front of the shoe, with a secure feel across the midfoot.
Are they waterproof?
No, the flat-knit upper is designed for maximum breathability, meaning it is not waterproof or water-resistant.
Troubleshooting
Feeling of slippage in the heel area
Try a 'runner's loop' or 'lock lacing' technique with the top eyelets to secure the heel fit.
Midsole foam feels less responsive after many miles
Running shoes typically lose cushioning integrity after 300-500 miles; if you are within this range, it may be time for a replacement.
Upper material irritation
Ensure the laces are not tied too tightly across the midfoot and check that your socks are moisture-wicking synthetic fibers to reduce friction.

Setup, Compatibility & Care
To ensure the longevity of your Brooks Glycerin Flex trainers, follow these guidelines:
- Break-in: While they feel comfortable out of the box, take a few short walks or light jogs to allow the nitrogen-infused midsole to adapt to your foot strike pattern.
- Cleaning: Remove surface dirt with a soft brush. If needed, hand wash using warm water and a mild detergent. Avoid machine washing or drying, as high heat can degrade the cushioning foam.
- Drying: Air dry only. Remove the sockliner to allow internal moisture to escape and keep the shoes in a well-ventilated area away from direct heat sources like radiators.
- Storage: Keep in a cool, dry place. Avoid leaving them in direct sunlight or locked in a hot car for extended periods to prevent structural breakdown of the midsole materials.
