Who should NOT buy it

If you're on a budget, stick with version 2 of the Nike React Infinity Run FK instead. There's not much difference going on, save for the looks and more padding. If you want a shoe from a different collection, the Nike Pegasus 38 is not only cheaper; it also performs similarly for $40 less.

If you want a shoe that "springs to life" and will "baby your legs" altogether, the Nike Invincible Run comes highly recommended. And if it's a lighter alternative you're after, the Puma Velocity Nitro 2 won't be a letdown. 

Nike React Infinity Run FK 3 vs. 2

A more supportive fit is the main highlight of the Nike React Infinity Run Flyknit 3. To achieve this, it features a more padded ankle collar and heel. Even more, it has a thicker Flyknit upper and Flywire cables for a better foot hold.

On the flip side, however, it "lacks the versatility of the original version."

A seamless ride from the Infinity Run Flyknit 3

Although it's not the lightest daily trainer on the market, multiple runners agree that the shoe doesn't feel "sluggish," thanks to its smooth transitions. Even better, the more they ran on their toes, the nicer and more seamless the transitions became.

Tips the scales

The shoe's rather bulky weight at 310 grams or 10.6 ounces in US men's 9 (vs. the average daily trainer at 282 grams or 9.9 ounces) has reviewers asking, "when will Nike make a light daily shoe?" They agree that it's: 

  • "quite heavy"
  • "clunky"
  • "getting heavier each time"

Takes care of the feet

Think of the Nike Pegasus but softer. That's the Infinity React Run Flyknit. It's "not overly squishy," but it preserves a good balance of firmness and softness; experts say the biggest thing about it is the level of step-in comfort they get straightaway.

So much so that they have used it for gym training, office, and walking around town, and even for all-day wear. And because it has a generous amount of cushion, heavy runners also find it really comfortable for jogging.

The shoe's firmness paired with its wide base keep a highly stable ride. Some even recommend it to help mild overpronators because they find it more stable than most neutral shoes. What's more, it supports tired legs.

Traction that bites

Road runners have NO issues with the shoe's traction. During their testing, they say it sticks well on wet concrete, treadmill, and light trail.

Just the right fit! 

Although not as sock-like as the first iteration of the Nike React Infinity Run Flyknit, more than 80% of the critics find the shoe's fit "secure." In the rear, the heel has sufficient padding; no one has suffered from heel slips. Plus, the upper is stretchy; it conforms to the foot.

In summary, this shoe's fit remains "unmatched." 

More than enough room

Unlike most Nike running shoes, the React Infinity Run FK 3 doesn't have a narrow toe box. It's spacious; "incredible" is how the many describe the comfort they get from it.

Even more, the upper's pliability helps a lot in bumping up comfort. According to most, even in areas where their feet pushed against the shoe, it never rubbed their toes. 

Not your budget-friendly trainer

It's a helluva pricey shoe. At full price, it's a "definite no!" for most runners. Given that it's better than v2 but not as great as the first version, it's really "difficult to justify the price."

Contrary to other daily running shoes, which cost $119, on average, its $160 price tag is without a doubt a lot of money.

A stunner

It "looks wicked!" Road runners give a "hats off to Nike." This is especially true for the pink and green color combo, which has captured the attention of many reviewers.
