I love love love my Nike React Infinity Run women’s running shoes! I’ll start by saying I sometimes have trouble with the fit of Nike shoes because they tend to be a little more narrow for my wider foot. I did not have that issue at all with these shoes! They are wider at the top which makes them very comfortable. They also have a lot of padding in the soles, which is something I am always looking for. I do a combination of running and walking most days and since I’ve gotten these shoes, I haven’t put back on any of my other sneakers. They are the most comfortable ones I now own. I have issues on and off with my knees hurting and I haven’t had this issue since I’ve been wearing these. I also look the look of these shoes- they are simple and the black and white go ... MoreI love love love my Nike React Infinity Run women’s running shoes!

Overall I wouldn’t change much at all about these shoes- they are extremely comfortable, look great and run true to size!

I have ran in several Nike running shoes, and I feel like those are the best shoes for me to test, and this pair was great! My foot is a tad on the wide side, and these shoes felt great! When running, I had proper arch support, but also, when sprinting, I felt that these shoes provided great support on the ball of my foot as well. The laces tie up at the appropriate spot on my foot, which may not seem like something that is normally called out, but I have purchased shoes before where the top lace holes are in the wrong spot and it makes my job very uncomfortable, not here though. The styling is great, which is a major bonus, as I hate to admit that I don’t care how great a running shoe performs, because if it looks lame, it’s not going on my foot - The shoe has got ... MoreI have ran in several Nike running shoes, and I feel like those are the best shoes for me to test, and this pair was great!

For some constructive feedback, my running shoe of choice is the Nike fly knit - This shoe will not replace the fly knit as my preferred shoe as this shoe doesn’t have the stretch I like to feel when running - It isn’t as light as the fly knit or as flexible as the fly knit. Would I purchase this shoe or recommend it - Yes, absolutely! It has great looks, feels great, runs great and it’s my favorite shoe brand for running.

Tried these on in the Nike store yesterday. First impression: heavy and boggy on the foot. Felt like bricks with laces. This strikes me as a lifestyle shoe that is suited for walking or standing, maybe for runners just starting out. Nothing wrong with that at all. Just appears the Nike React Infinity line is moving away from what I would consider a running shoe. In the end Nike still has the AF and VF for serious runners so it’s alright. Just not a fan of heavy training shoe with excessive squishy feel. I will not be running in these. These shoes look cool though and will serve a purpose for others, but just not me.

First thing I noticed was the cushion in the sole and it is amazingly comfortable for long walks or jogs. I've been using these for a few weeks and they have become my favorite jogging shoe. The react cushion is super responsive and hasn't flattened yet and I've used them pretty heavily in the last few weeks. The new woven material in the toebox is much more snug and doesn't get loose with extended wear. I've noticed sometimes these type of woven sneakers can loosen and let your toe slip forward but it doesn't happen with these. Also the cushion starting slightly further back and rounded helps with contact if your like me amn hard on the heel. Overall the style is suitable for any occasion sneakers are acceptable and isn't overwhelming. I like the simplicity so ... MoreFirst thing I noticed was the cushion in the sole and it is amazingly comfortable for long walks or jogs.

I love this Sneaker and it's been hard to convince myself to wear anything else lately to be honest. They slip right on and really make my feet feel better after a long day. Definitely would recommend these to anyone with sore feet but still wants to walk or run to stay in shape.
When first taking a look at the shoe my husband was not sure this was going to be a good shoe for him. It was different than any shoe he has ever worn. Given this, he was skeptical about how they would feel. He wore them a little each day (an hour, then two hours, then four hours) until he could wear them all day. Now, he likes how they feel when he walks and has gotten used to the higher heel of the shoe. He has not worn them for running yet, but walking has been more comfortable than in his former shoe. Since this is the first shoe of this kind, he does not have any changes he would make. He is enjoying wearing them and they have helped reduce his Achilles pain.
Oh my goodness. These are one of the most comfortable pair of shoes I've ever owned for jogging. Upon arrival, I thought they were a tad snug for the gym and for casual wear. I typically like a little more wiggle too . However, for running and jogging, they were a perfect fit and extremely comfortable. It wasn't until the third day that I ran in them. Prior to then, I biked, worked out at gym, and used them for walking around casually. They were broken in and my feet felt great during my 2 mile run. The cushion is like no other! With each step, I can feel the cushion give in the midsole and sole areas. The design is pretty good, plain black and white. It has a cool look to it. Nothing too spectacular on the design and color, but I truly mean it when I say the ... MoreOh my goodness. These are one of the most comfortable pair of shoes I've ever owned for jogging.

The Nike React Infinity Run FK 4 is a great new vision in running shoes for the modern day runners. Most of the running shoes I’ve tried in my life usually skew on the side of very lightweight and cushioned or very durable and rugged but with these shoes you have something in the middle that offers a well balanced supportive sneaker that is also lightweight and comfortable. The fit is very solid and has great support for the feet and the feel is on the bouncier side as if you are walking on a bouncy ball. They are well positioned to use on treadmills and running tracks and wherever you feel fit to run. The design of the shoes make you stand out from the runner next to you because most of them are probably wearing nikes and they all are similar designs and color ways ... MoreThe Nike React Infinity Run FK 4 is a great new vision in running shoes for the modern day runners.

The design of the shoes make you stand out from the runner next to you because most of them are probably wearing nikes and they all are similar designs and color ways but with these sneakers you can stand out with the swoosh pushed to the front of the shoes and a stability clip that people are going to notice. The fabric of the shoes feel very durable and supportive to give confidence that you can wear these shoes for a long period of time. My favorite aspect of these shoes would have to be design and the supportive cushioning to make my runs feel like I’m taking my cardio to the next level. The only thing I would change would be the bottom of the shoes wear the material feels very slippery on wet surfaces which people should be cautioned about but I understand in the running perspective this helps with the running experience.
The Infinity Run 4 is an amazing upgrade from the previous versions. I loved the flyknit upper of the first version and then the 2nd and 3rd version felt boring. This 4th version has reignited that spark that the infinity run series was loosing. The infinity run v4 uses Nikes newest ReactX foam that is bouncy, comfortable, and a bit more responsive than Nikes original react foam. The upper is a bit on the tighter side as most flyknit models (older flyknit that can be found on version 1, and 2018 free run flyknit) are, but it’s not super uncomfortable once you begin running. I don’t think going up a half size for this model would be a bad idea though, especially if you prefer a looser fit. The shoe is very easy to get on and take off and has a gusseted tongue so it ... MoreThe Infinity Run 4 is an amazing upgrade from the previous versions.

Version 4 is still just as stable as the previous version, but they got rid of the heel clip that would annoy some people’s arches. Overall, The if in
I really wanted to love these shoes but as everyone else has said, they’re just too small.For AF1 and non-Nike shoes I wear 10.5For Nike running and basketball I wear 11.I tried these in both 10.5 and 11 and they don’t fit. I may give them a third try, and if I do it’ll be a half size or full size up. They look and feel really good beneath your feet. It’s just that upper hugs far too tight when feet swell.I’ve tried Pegasus 40, these shoes, and Invincible 3.As far as fitment goes, the Pegasus 40 are true to size (10.5 for me). They’re also very firm underfoot, as anyone that uses React knows. When the weather turns cold, it’s very firm.As far as cushioning goes, I have two pairs of Invincible 3. They feel great, but that ZoomX sensation is almost wobbly ... MoreI really wanted to love these shoes but as everyone else has said, they’re just too small.For AF1 and non-Nike shoes I wear 10.5For Nike running and basketball I wear 11.I tried these in both 10.5 and 11 and they don’t fit.

The sole of the shoe provides comfort as if you're walking on clouds. The upper material of the shoe is extremely comfortable & feels no less restricting than a sock. While these comfort elements far outweigh the cons, I will say at times they felt a little unsupportive. However, I've struggled with ankle injuries my whole life so that may be more so product of my own circumstances. Overall, the fit, feel, & comfort of the shoe is far superior to other running shoes I've worn recently. The shoes have a beautiful minimalistic design in the black & white color way I have. As mentioned, the fabric of the upper material on the shoe felt like a sock & was just as breathable as a sock as well.

The heel sticks out a little too far for my liking. While very beneficial for running, I think the heel could have been a little less elongated and still realize the same benefits for running.
