[This review was collected as part of a promotion.] These shoes exceeded my expectations! They fit perfectly and provide enough cushion and support for me during my long work shifts which are spent mainly on my feet. They also work great for cardio at the gym and I plan to use them outside on trails at my weekly park run. I like the stretchy fabric and overall design of the shoe. It really helps having the loops in the front and back of the shoe to assist when putting them on and readjusting. If I could change one thing about the shoe it would be to make the material a little thicker or water resistant as I live in a city where it rains a lot especially this time of year.
[This review was collected as part of a promotion.] Brooks Running has exceeded my expectations with the Glycerin Stealthfit 21. I am a nurse that works 12-hour shifts who enjoys hiking and running outdoors. The Stealthfit sole has the stability and responsiveness that I was needing for both work and play. I usually wear a size 8 and they are a perfect true to size shoe. The design has a sock fit around the ankle with cushion support for the heel. The fabric used is breathable and has the ability to adjust to toe width. Overall, I could not be happier with their performance and would highly recommend them to all.
Great fit. Love the sock style upper. Super comfortable to run in. I’ve been a Ghost fan for many years but have needed more cushion as I age - hahaha. Only complaint - which has nothing to do with running - is that I can’t wear them in my HIIT classes that include both running and rowing. The heel is thick with cushion (not the problem) but it curves up in the back so the back of the heel doesn’t contact the ground making it impossible to use on a rower. Heel of the shoe keeps lifting out of the footplates on the rower. Love my 21s for running but now have 20s for HIIT classes since the heels on the older 20 model contact the ground.
[This review was collected as part of a promotion.] These shoes are great. I’m currently training for a 5k, but I’ve run several 10 milers and half marathons (my most recent half was 3 months ago). So I’ve gone through a fair number of shoes! I like the Glycerin Stealthfit 21 because they’re lightweight and very comfortable. This is my first experience with a tongueless shoe and I’m a fan-there’s less stuff to rub on my feet. I have a narrow heel and these shoes do not slip or blister my heels, so that’s awesome. The stability level is nice, I like that the shoe provides support without sacrificing comfort or shock absorption. My only issue is that the toe box could be a tad bigger. But that’s pretty specific to my foot, and it isn’t a big deal. Overall a great shoe! Highly recommend!
[This review was collected as part of a promotion.] I am truly in love with this shoe. I have been shoe hopping for a few months as everything I put on hurts. I’ve been nursing an injury and for once I feel like I can get back to my regular routine. I’ve been wearing the new glycerin since I got them and they feel like air. The sock like fit in the toe box is perfect for me. I have a wide foot, so finding something which doesn’t feel like I’m being squeezed into it can be a challenge. I’ve got two little ones (peep the blue paint in the pic) and I’ve been able to keep up after them with these as my everyday shoe. I did size up a half size and I am glad I did. Brooks do typically fit me pretty snug due to their design and my wide foot- but these feel great. Can’t recommend them enough.
[This review was collected as part of a promotion.] I really like the overall design of these shoes and how neutral the color scheme is. These provide a lot of support for my feet and there is noticeably great shock absorption when I'm running. The fabric breathes well so I'm not feeling like my feet are sweating or overheating at all. They have an almost sock like quality to them that makes them uniquely secure when I'm running in them that I truly appreciate. I highly recommend these for any avid runner or even someone just on their feet a lot that's looking for support and excellent comfort.
Bought the shoe for middle-to-long distance running, style, comfort, and snug fit. Having a difficult time getting excited about running in these again after two weeks of use (five days per week). With each stride, the soles rub mid cycle due to width and my run pattern. It's easier to run in a different shoe than change my run motion to adjust to a new shoe. It's a non-problem in the Ghost 14s. Wish I upgraded to a different Brooks option instead because now I'll need to save up to purchase something else—my G14s have run their course.
[This review was collected as part of a promotion.] I was pleasantly surprised with the Brooks Glycerin Stealthfit 21! At first appearance, I was slightly concerned with the lightweight, stretchy fabric. However, after using the shoes, the fit stays snug, comfortable and does not stretch out during use. The shoes are very breathable, so best to use warm socks while training in the cold. I have trouble with plantar fasciitis and these have not caused me any sort of pain or discomfort. Overall, I am very happy with this product and would recommend to my family and friends.
[This review was collected as part of a promotion.] Brooks has done it again!! I have been wearing the Ghost 15 but these are my new go to!! I love how roomy these shoes are! Tbey are true to size and fit well on my feet. They are so soft I can’t even describe it, it’s like walking in a cloud! The shoe itself is so well made and I love how the back of the shoe is stretchy and molds to your heel. I have not had any issues with rubbing or blisters even with running 9+ miles a day sometimes. The shoes have held up well so far and I LOVE the look of the shoe itself! I’ve washed these once in the washing machine and they came out perfectly! These shoes are stylish and functional! Compared to the Ghost 15 these seem a little wider and definitely more cushion, which is what I’ve been looking for! You definitely NEED these shoes!!
This particular style is very fitted around the entire foot. I have been wearing brooks for years (same size) and for some reason this seasons line runs a little tight and small. I want to blame this in the material and the padding on the inside. I was undecided whether I wanted to keep them but I’m pregnant and a nurse and needed a fresh pair stat and they were on sale (and no my feet aren’t swollen) They have stretched out a little after wearing but just note they are the tightest pair of brooks I have ever owned. I appreciate the extra support but wish the fit was slightly more relaxed. Size up a half on these!!!
