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.

I have dealt with chronic post tib pain throughout my running career. After switching to these shoes the pain shows up less frequently and less severely.

50 mpw training for a marathon came from the Mizuno Wave Rider 19

Overall
Let's be frank. I'm 30 pounds overweight and not getting any younger. But my old glory days still call to me and I want to give it another go. If I'm going to run off these pounds, I need to protect my knees (and all those other parts that are starting to hurt for no good reason). The Brooks Glycerin 20 is the best shoe that I have found that fits that bill. It is extremely cushioned and smooth. It's the Buick Park Avenue of shoes. And while I lose a bit of the sportiness and feel of the ground, the bumps have never felt smoother and I feel like I can run in these forever. That being said, if I get to a point where I don't need so much cushion, I will be moving out of this shoe and into something more aggressive.

I really like the Glycerin, they’ve been my shoes for 4 years now and they don’t give me much trouble, are pretty comfortable, and this new model looks soooo good in some color ways (namely the black with red and blue brooks logo). Outside of cost I can’t complain much about these shoes. I do put in custom inserts but that is to correct issues with the structure of my feet
