Within Brooks’ range of road shoes designed for daily training, runners can choose between three models (not including the Ghost series). We have already tested the Glycerin Max 2 (320 grams), featuring a 6 mm drop, making it heavier than the Glycerin 23 (300 grams). The Glycerin Flex, meanwhile, comes in at 258 grams, also with a 6 mm drop.
The Glycerin 23 has a higher drop than its siblings at 8 mm, compared to 10 mm for the previous Glycerin 22. Its midsole foam delivers substantial cushioning, but in a controlled way: the shoe doesn’t tend to drift laterally. Stability proved convincing for a road shoe built to rack up the miles. Cushioning is clearly felt under the metatarsals, and the foam provides a good rebound, avoiding any spongy sensation when running on the forefoot.
The smooth transition is enhanced by a forward rocker that some testers described as “natural.” We appreciated the dynamic qualities of the Glycerin 23. With this shoe, miles go by efficiently—and above all, in great comfort. Of course, this is not a racing shoe like the Hyperion, but rather a versatile option for everyday running and even for taking on longer-distance events.
The shoe looks great and is very well finished. The mesh upper is excellent, the tongue is comfortable, and the lacing system is both easy and precise. Heel hold is solid, and the shoe is easy to put on thanks to the heel tab. The outsole provides good grip on the road. An excellent alternative to the Asics Nimbus.
We particularly appreciated its high level of comfort combined with the energy return of its midsole. A dynamic shoe for enjoyable daily runs. First Test4outside Award.
