How it ranks
The Brooks Glycerin 20 is one of the strongest daily trainers in our data. Durability and comfort are its strongest sub-ratings. Looks scores well below its other sub-ratings. The rating rests on 50 runner reviews and 12 other rated shoes in the Glycerin product line.
Confidence
How settled the rating is against every other rated shoe. A shoe can rate high on confidence with relatively few reviews of its own when its product line has a long record and external ratings from retailer sites agree. Confidence will score low when we have few ratings or when runners disagree.

Overall
Switched to glycerin due to foot issues and needing a wider shoe. Worked like a champ and great cushioning. Now Brooks needs to offer some wider widths in a racer.

20 mpw training for a marathon
4/5
Overall
The shoe has big slabs of foam and is soft. It's pretty durable due to all the rubber on the outside. It's relatively stable due to high side walls. But it's heavy and runs a bit small (I went a half size up). I found my shoes for $60. They have bizarre colors that are bright and ugly. But even so for the prize good shoe.

35 mpw training for a marathon came from the HOKA Clifton 9
4/5
Overall
The Glycerins are amazing, especially for people with high arches, and they feel springy and cushion-y, especially during long-middle distance runs. They are also quite comfortable as dailies, even though where they really stand out is support during running. It is also the shoe that stopped my chronic knee pain when running.

23 mpw training for 5K and 10K came from the ASICS GEL-Cumulus 25
5/5
Overall
I switched to these from Hoka's, which didn't seem to hold up well after a couple of months. I did a foot evaluation at my local Fleet Feet and they suggested the Glycerins. I am now running in my 4th straight pair! I love the comfort and durability of these shoes. They provide just a bit of stability but not enough to notice. Great trainer and I highly recommend.
