  • The Phylite is a Nike’s midsole technology, which is created from a combination of solid rubber (40%) and Nike-exclusive Phylon (60%). This helps enhance durability and at the same time offers more flexibility to the shoes.
  • The Beveled heel in the outer sole of Nike Free Flyknit encourages runners pursue a natural gait through promoting better forefoot and mid-foot striking.
  • The Flyknit Upper has a seamless design that provides a customized and sock-like fit. The upper is also made of lightweight material to keep the weight of shoes at a bare minimum and improve breathability and resiliency.
  • The Transtarsal flex grooves of the midsole are integrated into the outsole in order to provide enhanced flexibility and mobility to runners.
  • Waffle lugs designed in the outsole work as additional cushioning and protect the foot from landing impact and the underfoot from road debris and shock.
  • The BRS 1000 carbon rubber weaved through the waffle lugs in the outsole provides excellent traction on both dry and wet surfaces while enhancing durability and wear-resistance of the shoes.
  • The molded sock liner of Nike Free Flyknit is a removable unit made from compressed EVA foam, which adds more cushioning to the shoes. Besides, this molded sock liner also gives a more customized fit as well as assists in absorbing impact during landing.

Nike Free Flyknit 5 review


Knit uppers are very light, very comfy and fit like a sock. The upper is designed to conform to the foot. Additionally, for ventilation, this part is designed with air pockets in the toes to allow airflows into your shoes and has a Flyknit panel to help dissipate heat.


Carved with the same sip configuration as the outsole, the midsole also encourage freedom of movement and a more natural running form. Very durable foam used in the midsole is a blend of solid rubber and the Nike-exclusive Phylon at a ratio of 40/60, which provides not only excellent durability but also an adequate responsiveness.


The outsole is made up of a very soft foam-like material with hexagon pattern cuts, which allow for an impressive amount of flexibility. During your run you will notice how the outsole’s pliability allows your feet to achieve a fuller range of motion. Nike uses a beveled and decoupled heel to offer better ground contact, helps with the transition, and isolates shock. Be careful running on gravel roads because rocks occasionally get stuck in the outsole; fortunately, you will be able to remove them easily due to the elastic BRS 1000 carbon rubber used in the outsole.

Heel to toe drop

Runners will be happy to know that the Flyknit Free running shoes have a low heel to toe drop because this feature will encourage a more natural running technique and a barefoot running experience.


Generally, Nike Free Flyknit 5s are very soft and comfy. The soft materials and sock-fit design of the upper allow me to feel comfortable in the shoes even without wearing socks. They don’t cause any blisters or irritation to my skin. I've worn them for short distances races and they are comfortable from the beginning to the end. There are no hotspots or blisters, no lost toenails on long runs. I can also put on and remove easily without taking the laces off.


They fit snugly on my feet like socks. Both the design and material make the shoes hug runners’ feet. When you tighten the laces, the entire shoe morphs to be tighter on the sides of your foot opposed to just having the top part squeezing to walls of leather together. But because of being designed to conform to the foot, Nike Flyknit Free is worn without laces. I was suggested to get a half size larger than my normal size and they fit me well.


The Nike Free Flyknit shoes are neutral trainers so certainly they have lesser cushioning than other stability and motion-control shoes. These shoes provide just enough cushioning to keep me from feeling every little rock on the road and make my feet look nice and comfy during a long run. The heel cushioning is low enough to enhance natural running technique but still provides good shock absorption during heel striking.


Nike Free Flyknit is considered as a neutral shoe, which provides necessary stability and support to control under pronation. They have many supportive features. Flywire cables provide support without adding more weight to the shoes. However, there are not tons of arch support or padding underfoot, so they are probably not the shoes for you if you have bad arches and need a lot of support or cushioning.


The revolutionary fabric used to make the upper is very light and cool. Knit-in ventilation holes designed at the quarter panel enhance breathability of the shoes. Airflow is allowed to come in the shoes for better ventilation. Moreover, a Flyknit panel helps dissipate heat to prevent foot from getting hot. Thanks to these great breathability properties, Nike Flyknit Free 5s are the perfect summer sneakers!


The Nike Free Flyknit shoes are very flexible to give you natural range of motion in any distance. The sole is firm and supportive yet due to the segmented honeycomb cuts, they still allow a lot of flexibility.


Nike Free Flyknit 5 is a flex shoe instead of a stiff one. Therefore, stability rating of these is lesser than other stiffer shoes. More stability could affect flexibility and natural gait of runners. Although there is a small amount of stability, it is not too bad. Because the shoes are neutral runners and used to encourage barefoot running experience so a lot of stability is not essential.

Quality and durability

I walk a lot on concrete and was a little concerned that they may not last long. And after several months of usage, they are still working well without any sign of wearing out. You can probably just throw them in the washer without any problem. Nike enhanced durability of the Free Flyknit through a rubber outsole. You will be surprised by its resilience. Although it feels very soft, it doesn’t break down easily. But if you compare these to other running shoes of Asics or Brooks, they are not solid ones and their durability seems to be less.


Nike Free Flyknit has flat under surface that is suitable to be used on roads, tracks and gravel terrains. The rubber outsole with waffle lugs seems to increase cushioning against slight road debris and pavement impact. They also have superb traction and grip to perform well on both dry and wet surfaces thanks to the BRS 1000 featured in the outsole.


Weight is usually a determining factor of shoes in running. In other words, this factor determines what kinds of activity the shoes can be used for. No one wants to run in heavy shoes. Caught this tendency; Nike produced a lightweight model like Nike Free Flyknit. They are rated as one of the lightest neutral shoes in the market. The weight of men’s version is 215 grams while the women’s weighs 172 grams. They indeed make me feel like wearing nothing at all. With a cloud like running experience, these will make you want to run faster and farther than ever before.


Nike’s shoes look pretty awesome. They have a sleek design with vibrant color combinations. Whether you are looking for flashy colors or just a simple black and white pattern, I think you’ll find what you are looking for among numerous options. With a cross-marked design and pebbled color scheme, you will not have to worry if you get these shoes dirty. The dirt blends in with the dark color scheme making these great new look last longer.


I use them for work and cross fit, walking and even speed training or a road marathon thanks to the soft and lightweight features of the shoes. The softer sides offer little support to keep your foot on the sole during more active sports; so don't use these shoes for anything that requires firm shoes. They have less cushioning so they are great for practicing a natural gait. They can also serve for barefoot running. However, because of little support, these are not good for sports/activities with lateral movements. Besides, I would not suggest using them for hiking in the woods because the mesh can be easily torn if scraped against branches or rocks.

The shoes come in a bit expensive. People had to think very careful before deciding to purchase a pair of these. And after using, all of them feel satisfied with their investment. Read the information above and determine whether the shoes meet your needs. If they provide all the properties you are looking for, don’t hesitate to buy a pair immediately.​

Similar running shoes to Nike Free Flyknit

Base on design, features as well as benefits that the shoes bring to runners, I think that Nike Free is the most similar model to Nike Free Flyknit. The price of these is a bit cheaper than Nike Free Flyknit but they are still packed with similar minimal features. BRS 1000 carbon rubber is used to make the outsole that enhances durability of the shoes and provides great traction to deal with tracks, roads and gravel terrains. Besides, these shoes also have other same features that you can find in Free Flyknit such as the Dynamic Flywire, waffle lugs, Transtarsal flex grooves, Phylite foam and so on. If you are mild pronators and looking for training shoes that can provide excellent protection and shock absorption while promoting a natural gait, The Nike Free will be surely the best option for you.

Additionally, the outsole is also designed with non-aggressive pattern that offers superior traction to deal with wet and slippery conditions. The weight of this version is also reduced which is very ideal for speed work and improving performance.

More specifically, the heels of shoes have the ability to mimic the heel shape of runners that is very useful for those who want to pursue barefoot or minimalist-inspired running. The molded Sockliner also complements this feature, which conform to every curve of the foot to encourage more natural running styles and practice techniques. Most of the minimalist running shoes don’t have a lot of supportive cushioning in them. However, The Flyknit 3 has enough arch support and needed stability to decelerate pronation, especially, to cater runners who have under-pronation.​

This version is well known for its sock-like fit and lightweight.

The Transtarsal Flex Grooves and the Nike Free Sipes still present in the 2nd version to provide and enhance essential flexibility. Like other Nike running shoes, BRS 1000 carbon rubber is used to make the outsole of Free Flyknit 2 for improved durability and traction to run well on roads, tracks, pavements and gravel terrains. This minimal outsole helps the foot have looser contact with the ground for a more natural running movement. This model is designed for runners with medium or high arches who can run well without arch or medial support. They are also called neutral pronators and supinator. Moreover, Nike Free Flyknit 2 is indeed a versatile shoe because it can be used for many purposes such as speed workouts, daily running, cross training, fun racing or marathons or other casual activities.​


I was extremely impressed with the nice comfort and fit, stylish and durability Nike Free Flyknit 5 delivers to me and I highly recommend these shoes for runners of all skill levels, especially for runners who plan to do the transition from traditional shoes to minimalist ones.
