Very Flexible For A Good Road Feel

very flexible shoe which helps it to feel lighter than it actually is. I need lightweight flexible shoes or my feet will hurt. After years of minimalist running i am looking for a shoe that adds just a little cushion, now that i am getting older, without sacrificing the flex and road feel that i love with minimalist shoes. I originally switched to Brooks from Nike, and the Hyperion 2 were my first Brooks shoes, and i LOVED them. However the newer ones, the Hyperion 3's, have not gotten good reviews and look to have strayed from some of the things i loved the most about the 2's. Just the look of them do not look like Hyperion's. I was very close to switching again to Saucony, and then i saw the Glycerin Flex pop up as a completely new shoe. It seemed to have what i was looking for, albeit a little on the heavy side, so i decided to give them a try. My first run with them was on a very windy day. Not the best day to fairly judge a new pair of shoes, because the new shoes will always get the blame if you feel you are struggling a little more than usual. I did notice they are very flexible and kept me feeling connected to the ground. This all helps to promote ankle and lower leg strength, which i have become accustomed to with minimalist shoes, and i did not want to lose that. the flexibility of the shoe made it feel lighter than what it actually is, and it has the right amount of cushion without becoming a marshmallow shoe, which i hate nowadays. now for the reasons i deducted 1 star. After a 5 mile run, i noticed a few "hot spots". one was on the inner portion of my foot kind of where my heel transitions to my arch. And the other one was a spot on the bottom of my big toe. I wont be too critical of this yet, i had a couple hotspots when i started running in the Hyperion 2's, but after a while, my feet seemed to adjust and i didnt have any issues. The other negative, i HATE the laces. Big, fat , chunky laces are the worst to use in running shoes. Even after double knotting them, i was afraid they were going to come untied. The laces in the Hyperion 2's, are the best laces you can put in running shoes. Skinny and with ridges to help keep them tied. I will be replacing with some caterpy laces. Just another FYI, they do feel a little tighter around my feet. Could be designed that way for a reason, or could just be a narrower shoe

A Step In The Right Direction!

I typically wear a women's 8.5 wide or extra wide and often have to hop over to a men's 7 wide to accommodate my foot shape. These just didn't work, unfortunately (perfect length, but too narrow along the sides), and I did return them. But my rating is not about the fit. I was eager to try these because the only shoes i've ever found that allow me to move 'naturally' are Nike Free Runs, but they are not supportive enough for regular wear. Brooks is really on to something here and I am excited to see where these shoes will go in the future... these are a major step in the right direction! (and bonus points for a legit fantastic upper). There was clearly a lot that went into the engineering of these shoes, with good intentions, and surely a lot of people will love them. For anyone wondering about a comparison, they did not move as naturally as the Free Runs, to me. The Free Runs offer the same amount of flex, or flexion along the entire length of the shoe, whereas the Glycerin Flex have a fixed heel with a flexible forefoot - and it was that 'split' that felt unusual. In the short time that I tried these it felt as if during my stride there was an unnatural stretch along the arch of my foot - as if my natural foot movement was disconnected. It may be that this is a healthy movement for the foot and just felt strange to me - I really don't want to steer anyone wrong. I can't say if it would have been good long term. My foot could not tolerate the narrow shoe long enough to give them a more fair shot, so please take this with a grain of salt. I am stoked that the market is heading in this direction and will eagerly await future iterations of this shoe! Thank you Brooks!!!! Note: for anyone thinking 'wait, if these are too narrow, surely the Free Runs are too narrow, how can you wear those?' you are correct! The rails on these were harder. The Free Runs are so soft I can tolerate the slight edge underneath. These had enough structure (a good thing for most) that I felt like I was over the rails and it was both uncomfortable and unstable. Ideally, a future iteration would offer a better foot shape (less pointy, more rounded) and more width options. One can dream! If you're still reading because you are also a Free Run hoarder, you'll be glad to know the Glycerin Flex does not 'collect' small stones in the grooves. I ended up with maybe one or two, as opposed to one in literally every nook and cranny:)

Best Shoe From Brooks In Past 10 Years

I have not been happy in a Brooks shoe since they discontinued the Pure Project shoes. These shoes are perfect for me. They have a moderate heel to toe drop, are super flexible, provide good cushioning, have a wonderful stretchy upper, and the toebox is wide enough to accommodate bunions or wide feet. With the shoe industry focus in recent years on carbon plates and extreme rocker design, my rigid feet have not been able to find a flexible shoe that I am comfortable in for several years. Thanks Brooks for acknowledging that runners are different and we need different shoes!!!

Surprisingly Comfortable And Stable

My favorite road running shoes to date. These feel surprisingly stable for a maximum cushioning shoe and feel comfortable in all ways. I especially love the uppers, their mesh is forgiving yet snug and form to my foot to keep them locked in but not rubbing, in spite of my wide toe box and narrow heel. I never thought of choosing brooks but in comparison to the competition in the 5-6mm drop category, these are the clear winner for me. Well done brooks!

Seems To Push Into Supination.

Nice shoe and really wish they were great but it feels like the pod that is on the inside of the forefoot (think bunyon) is slightly taller or just more dense than the rest of the sole. This causes a feeling like the shoe is pushing me into supination (I have a neutral roll) and creates a hotspot on that inside part of the foot. Used the shoe finder on the website and this is the shoe it recommended and since I do a lot of gym workouts was hoping this was the one. Not so sure yet.
