I’ve never had the glycerin max, but I have had the glycerin 19, 20 and 21 they all worked out great for me

Brooks Glycerin 22 or 24, or Brooks Glycerin Max are great options Max more cusion and standard glycerin great balance of comfort and stability.

Sales + runrepeat. Needs to be at least half off. If I’m being honest more like 66%+ off. I’m running in speed 2s, Boston 11s, triumph 19, and glycerin 20s because they were on sale.

The test seems accurate to what I've seen with the shoes I have (Mizuno Wave Sky 8 and Brooks Glycerin 20).

My shoe purchases this year: Nike Vomero 16 (£59.99) Brooks Glycerin 20 (£73.80) Mizuno Wave Sky 6 (£54) I haven’t paid full-price for a pair of running shoes since Vomero 1 came out, and that was only because the store did an excellent job with gait analysis that helped cure longstanding shin issues. Never buy budget shoes - buy great shoes at good prices from previous seasons.

I mean I have two pairs of budget running shoes just so I can swap between them during my training. I just pick one of them for the actual marathon. Personally, I currently have Brooks Glycerin 20-ish and Mizuno Wave Rider somethings. I think I ran my marathon in the Brooks. But fitment is specific to each person.

Nike structure wide Brooks glycerin wide or extra wide If you’re into trail running Altra lone peaks These are my favorite as someone that’s a 9.5 women wide.
