I bought these for my 14 year old son to wear to school. He’s very active but only wears these to school and doesn’t wear the for sports or activities. I typically spend a good amount for shoes that will last. These were expensive and they didn’t last at all. The air cushion sole has several huge holes in them at this point. At one point when there was a downpour and when he got inside the soles had water in them. It’s so bad he squeaks when he walks lol. The rest of the show has been great. At the end of the day of a sole of a shoe can make it with basic wear and tear, the shoe is worthless to me. I’ve bought many Nike items without problem so I’m not against them. Just thought buyer should be aware when purchasing these.

I have owned my pair for a few months, and have put a several miles on them now. I have worn them on some trails in Utah, near open fires, and just to work and around town. They fit snug if you like that feel, but they are not as comfortable as my Renews. I was hoping that they would be more worn in at this point, but they may take more time (i hope).The only real negative I have is the sound of the rubber soles on surfaces. Obviously, the soles are unique, but they are rather loud on any surface other than earth or carpet. If you have hardwood floors, or tiles, be prepared for the constant squish of the rubber. They are much louder than any other Nike shoe I've purchased. Even after scuffing them up as much as I have, they are still as loud as day one.

The Vapormax 2021 is an okay sneaker but, in my honest opinion, not worth the premium price tag given the other options that Nike offers at similar price points. The Vapormax 2021 is definitely a step up from previous with the improved air unit providing better stability and the traditional laces, rather than the pully lace system seen on the Vapormax 2020, but the problem of stability still persists in a lesser fashion due to the almost cleat like feel under foot. I'll admit that I like a little bit of extra room, not too much though, in my sneakers just for some added comfort but the Vapormax seemed to provide too much of that when I went with my usual size of an 11 so I went down half a size to a 10.5. Downsizing helped out but also highlighted the fact that the ...

Downsizing helped out but also highlighted the fact that the Vapormax 2021 is a very narrow sneaker and now the sneaker. If you have a narrow foot you should be good with going true to size or maybe even downsizing by a half if you like to have a tighter fit, but if you have a wide foot I highly recommend going a half size up to get little bit of extra wiggle room in there. All in all I think that the Vapormax 2021 is a vast improvement over previous models, with the traditional laces and the improved Air Unit, but I think that the persistent lack of stability with these sneakers even after being improved up with the minimal comfort that they do provide makes it so that I can't recommend these sneakers at the premium price point that Nike has them priced at when Nike already offers other options at similar or cheaper price points that are a much better sneaker than the Vapormax 2021 is. Only buy the Vapormax 2021 if you're already a fan of a previous model and want a new one, you're curious to see for yourself what this silhouette has to offer, or if you want to have something to use as a fashion statement.
Haven't had a pair of vapormax before but loved the airmax360. These are more rigid almost like a soccer cleat (or football boot for ya Ted Lasso wankers). Because of the footbed's air pattern, the sole is lumpy and so I don't recommend on a rocky ground. Turf and grass would be okay but you're picking dirt out. Overall, they LOOK fast and turn any lazy pair of sweatpants into "athletic joggers" when running to the grocery store.
These shoes make you feel like your walking on a cloud. The comfort of these shoes are superb- even more comfortable than my sketchers which are my go to for comfort PLUS they are very STYLISH. The design of the shoe is well thought over- for the most part. The bottom of the shoe is made to withstand impact and can withstand sharp objects in most areas. However, certain areas are vulnerable to puncture which can flatten the air out of these pricey bad boys. Not the biggest concern but one none-the-less. Overall though, the pros outweigh the cons. Would definitely buy again!
I personally believe that these are the best and most comfortable shoes from Nike. I have tried a number of brands and a number of styles and nothing fits better than a vapormax. The fit like a glove to your feet and provide you with that extra bounce you need to keep your day going. I play basketball and I used to wear slides to and from the game until I discovered vapormax. Now I wear vapormax to and from the game because of comfort and they also provide a stylist look. My only dislike about this shoe is that on the exterior of the shoe facing inside after a long amount of wear there is a small tear on both shoes. How this my be a one time thing. I still highly recommend these shoes and if your still not completely sold I have 13 pair of shoes in all that all fit ...

They are not all this style however all 12 are vapormax.- Jace
I wear a women’s size 8 in these shoes and I love them! The woman’s version that is, but all in all a fantabulous design, look, and feel! I would rate 5 stars, but paying over $100 for a pair of shoes that probably didn’t take that much money to make a pair of these with reusable material. So 4 stars!
I love the shopping experience here to store online. Because it offers so many varieties. Oh outfits already chosen for the shoes. There's so many different options already picked, To help you what your style is that you're looking for. They have all sizes that you need. The different styles of shirts shorts pants is endless. I love shopping at the store. Every time I from here to the store to shop, it is a great experience.
I have the vapormax fk2 and I think they very great!The 2021 are more stable and very comfy but toe is a little narrow vs the fk2. I was a little disappointed in the foot bed or insert!! I looked at all my air max and flynitt from back to 2009 and all inserts are the same material or make up. With your recycling is fine but inserts are terrible. My feet sweat more and the insert is not soft anymore. The insert kinda feel rubbery to me. DO NOT like them at all. I wore new socks also and they pretty much beat them up and they are EXPENSIVE socks. DK why you would change something that was working great for a couple decades. Would recommend the shoe but cannot say anything good about the new insert. I bought two pair. One from finishline and 1 at nike. I dislike the ...

I refuse to ruin all my socks. Awesome running shoe though
