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

I started with Nike running shoes, I forgot what kind. I think they were too narrow because they would make my outer toes go numb. Right now I'm on my second pair of Brooks Glycerin 20s and have no issues

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.

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.

Glad you asked. I just started running again 6 months ago. We are same height and weight too. I’m 48. My last 10k I ran was also a 54 min effort. Here is my rotation: Fast tempo runs and intervals: Brooks Hyperion 2 and some old Saucony Endorphin Pro 1’s. These are lower stack and lower to the ground and light weight and fast. Perfect for fast efforts under a 10-15k max distance. I’m going to get a pair of the Hoka Mach X2 for this category as well. My everyday runners for most of my regular runs: I have two pairs of Saucony Endorphin Shift 3’s and a pair of TYR Valkyrie Speedworks. I had a pair of Salomon Aero Glide 3’s that fit this category as well. Those were some really fun soft daily trainers—the Salomon’s that is. I’ve got a pair of Adidas SL2’s that will fall into this category on the way from the current Adidas sale that’s going on. For my long runs over 10 miles or for my slower recovery runs: SuperBlast 2 and I had a pair of Brooks Triumph 22’s, but I’m going to be getting a pair of the Hoka Mach X2’s that I will use in this category as well possibly. Also the Puma MagMax Nitro is on my radar. I also just bought a pair of the Adidas Supernova Prima to try for this long run category as well. When I started running 6 months ago I was running in a pair of the Brooks Glycerine 21’s and did every run in them. They were fine for that but once I started adding some different shoes into the mix I started learning the value of having a shoe rotation. Jump on YouTube and find a guy named Yowana. He’s a pretty sharp guy who runs a lot (100+ miles a week) who has a knack for doing good shoe reviews and he’s also interesting to listen to him talk so I suggest finding his channel and checking out some of his shoe reviews. He’s a wealth of running shoe knowledge and experience.

Yes! I had the same experience! I have the Brooks glycerine 20 and they have a thick cushion, but nothing like the new 22s. I felt like I was falling off the heels. I bought a pair of 21s to see how I feel about them, but I'm hoping the Hokization trend ends. I didn't buy Hokas last time because I don't like them. Don't turn my Brooks and Asics into Hokas!

If you’re just starting out and mostly running for fun I would recommend something like a brooks glycerin, ghost, or adrenaline. They’re similar to each other but one is neutral, the others supportive. You can confirm which is which online. But either of those should feel like a great upgrade from what you’re currently using and should be a great all around running shoe to get started with, especially if you’re not able to get to a store like fit2run or fleet feet to do a analysis for you. They’re pretty great middle ground shoes in terms of tech bc they have a good amount of cushion, they’re not too stiff, not super heavy, no plate, etc. I’d try something like that or similar until you have been running for a bit longer so you can figure out what you prefer and then upgrade accordingly later on.
