Customer Reviews Brooks Glycerin Flex

I was so excited about the new Flex. I’m a long time fan of the Glycerin Stealthfit and I have quite a few generations of the line. The Glycerin has been a fabulous running shoe, and I have very comfortable runs in them. I’ve started buying other brands, however, because I need a shoe that provides more than just decent cushioning for running at the gym. I thought the Flex would do that for me because of its design. Out of the box, however, I’m not so sure these are a keeper. I size up to begin with (from an 8 to a 9) but I feel like I need to size up from my size up (to a 9.5). The tongue also seems like it’s going to be a problem, either because it seems challenged to lay flat and also because it also comes up high, which could irritate. I’m also worried that I’m sacrificing some overall stability with these.

A soft comfortable shoe. I fluctuate between 8 1/2 and 9. I got the 9 and it’s perfect. Hugs my foot, and nothing pushing or pulling. Best Brooks shoe I’ve put on my foot!

The most comfortable and supportive sneaker I've ever had. My shoe size is 6 but I always go up 1/2 size for sneakers and 6.5 was perfect. No break in time needed. I have a narrow foot/heel and these are perfect.

I walk 13 miles a day so I am very picky about my shoe fit. The Glycerin Flex feels so good!!!

I walk 12 to 13 miles a day so I am picky about my shoes. These felt great when I first put them on.

Excellent overall comfort and fit except for the length. I tend to be between 7 and 7.5 in running shoes, lately choosing 7.5 more often. But this shoe seems to be a little longer than recent purchases. Will try 7 instead.
