A very versatile sneaker. These runners are very comfortable with its knit upper and sturdy midsole. With its upper being a knit-like material, it is very breathable and not itchy or rough like other knit sneakers. The color is as versatile as it gets. Black and white, still in style which I like. You can throw on any outfit and wear these sneakers in every occasion if you want to. The outsole also has very nice traction for running and casual walking. I would say though that the runners do run a bit on the smaller side, so I would recommend going a half size up to a full size up if you have wide feet. With that being said, being a knit-like runner, I didn’t feel unstable or where my foot would leave the insole because the knit is too soft. The knit is sturdy where ... MoreA very versatile sneaker.

I really like these women's Nike React Infinity Run FK 4 shoes. The material is super lightweight and form fitted. The fabric is breathable which is nice for my active lifestyle. I took these on a camping trip and used them for jogging, long walks, and adventuring through the forest trails. They are very comfortable. The thick sole adds an extra, comfortable cushion which is what I love most about these shoes. I really like the simple design. Can't wait to get them in other colors! I do not have any complaints about these shoes.

At first glance I liked the thick sole of the shoe which is what I look for in a running shoe. I put the shoe to the test by wearing them to a baseball game with a lot of walking. They seemed a little narrow at first, but the stretchy material on the top helps with that. There is a lot of support in the heal which is where a lot of my weight goes when standing, so I loved that. If I wear them for a full day on my feet, by the end of the day my toes do feel a little squished, but no other part of my foot hurts. Overall, I loved the comfort, but my feet may just be a little too wide to wear them for a full day. For running and not wearing them all day, they are awesome.

I will start of by saying I do most of my walking and running on trails, with that being said these aren’t my favorite running shoes for unpaved trails. Overall I love the look and think that they have great support but would probably be better suited for paved trails or a treadmill. I am usually a 8 in most shoes but sometimes have to size up to ab 8.5 in Nike. For me these fit true to size and look super stylish. They have great arch support but are a little heavier than a few of my other running shoes. I would say they’re perfect if you plan to run indoors, on paved terrain, or in shorter intervals. They only started to bother my feet a bit around mile 3!
These sneakers get me pumped to go to the gym. They feel bouncy and get me energized. I feel the difference when walking on the treadmill in these compared to my other sneakers. They fit true to size and feel extremely comfortable. The fabric is durable, and the black and white color scheme is sleek. The one thing I would change about these shoes is the design of the front of the shoe. They look so large and rounded that they kind of remind me of clown shoes. My boyfriend says they look fine, but every time I put them on I can’t stop thinking about how big they make my feet look. I wear them to the gym only because I truly love the way they feel, but I would not wear these casually. If you’re looking for a good workout shoe, I’d definitely recommend them.
These shoes are pretty cool. I do not own a pair like these. The material on the upper part of the shoe I believe is flyknit if I'm correct and it makes the shoe fit like a glove. I would recommend staying true to size. I've used these shoes for the gym and will continue to do so. They feel great on feet and not mention they look great on feet as well. I've gotten a few compliments when I've wore them out hanging with friends. Overall this is a great gym shoe that happens to be very stylish.
I love this pair! As soon as I started walking, I could feel the bouncy feeling from the feet, which I love!! It feels almost like Invincible but more stable and steady. I hope the cushion or bottom of the shoes last longer since the Invincible did not last long. The shoe lace part felt a little bit tight when I walked, but I think I can make it better by loosing the laces.I have Hoka Bondi 8, which I love, too and was going to order another pair. However, I am glad I ordered this Infinity RN 4!! I want to purchase another pair.
The new look of the infinity 4 is so awesome. They look sleek and comfortable. The heel provides just the right cushion and walking around is amazing. The tongue has a soft not quite velcro Nike tag that helps to keep the laces tied all day long. The toe box on the shoes is average width that works well with my feet, my toes didn’t feel squished.My first longer run (10k) I took these out for a try the first few miles they felt great then I noticed my feet shifting forward and hitting the top of the toe box. There is a bit more of a drop in the shoes then I noticed previous so I needed to readjust my stride.A few runs later and I am getting used to the drop and my toes aren’t having as hard of a time as the first.Overall the shoe feels very well made, the material ... MoreThe new look of the infinity 4 is so awesome.

The laces are great they don’t come undone.Once you have worn then a few time they are wonderful.
I typically use my treadmill for walk/run workouts three to four times per week. I received these shoes in my normal running shoe size and I found them true to size. I didn’t need any break-in time and I was able to wear them for a full workout without any unusual discomfort. I really like the upper because it provided both comfort and stability. It feels very adaptable to the shape of my foot without the rigidity that some running shoes have. I also appreciated the cushioning that seemed appropriate for a casual runner like me without being too much. I didn’t feel any rubbing or pinching and traction felt good too. The design is pretty basic. Nothing really stands out but it’s pleasant looking. The sole is not overly thick but definitely noticeable because of the ... MoreI typically use my treadmill for walk/run workouts three to four times per week.

The design is pretty basic. Nothing really stands out but it’s pleasant looking. The sole is not overly thick but definitely noticeable because of the stark color difference between the black upper and white sole. I wore these shoes for multiple runs and they seem to be durable. No scuffs or tears yet. Judging by the quality of the materials, I don’t expect any visible wear anytime soon. Overall, I really like these running shoes. They give me all the functionality that I need to feel comfortable and supported. If I had to pick something to change, I would add some more design features like a pop of color on the logo. From a functional standpoint, I have no complaints.
The W NIKE REACT INFINITY RUN FK 4 is a very durable shoe. I like that the shoe texture is very smooth and feels wavy. The shoe itself feels very bouncy and gives you a boost when wearing them. These shoes are ideal for running and gym wear. My favorite part of the shoe is that it the color black. So that way the shoe doesn’t get dirty quickly. One thing I would change is to make the nike logo small. That way it’s not so much in your face and very simple. Overall it’s a great shoe that can be enjoyed by all age groups.
