Product Details:

Sizing Note: We recommend ordering a half-size larger than your usual size.

The Nike InfinityRN 4 has been completely revamped to get the most out of every workout, regardless of the mileage. Its new ReactX foam midsole reduces the carbon footprint by at least 43% compared to React foam without compromising its soft cushioning and responsiveness. The shoe features a redesigned rocker design that ensures a smooth transition from heel to toe, resulting in an exceptionally smooth running experience that makes each step feel easy. 

In the upper, the highly breathable Flyknit material keeps your feet cool and comfortable even during the toughest workouts, and for added stability, a Flyknit fit band in the midfoot ensures a secure lock down at any pace. The fit offers premium comfort thanks to the Flyknit Tongue and padded heel collar, and the outsole has been upgraded with blown rubber, enhancing traction on various road surfaces.

Whether it's a daily training session or any other running activity, the Nike React InfinityRN 4 delivers a trustworthy and well-cushioned underfoot experience for any daily training session.

Things You'll Love:

  • Soft and smooth ride
  • Inherently stable experience

Infinity run 4Excellent shoe, provides superior support and comfort. I put between 35-39 miles per week on them- shoes are perfect.

Great daily trainerThe Infinity Run 4 has been a great daily trainer for me this summer. I've logged a lot of miles in this shoe. The heel lockdown and overall fit are exceptional. The shoe has plenty of cushioning and still has pop for picking up the pace. I love running in this shoe. I did go up 1/2 size from my normal size 12 to 12 1/2.

They are growing on meInitially the shoe felt way too tight. My foot started cramping up because the material did not have a lot of stretch to it. I am not sure if I am just getting used to it or the material is stretching because they are feeling WAY more comfortable now that I am several runs in to this shoe.

Nice Daily TrainerI use the shoe has a daily trainer for LSD runs. It’s got plenty of cushion and a roomy toe box. You need to order up a 1/2 size. I do find the upper to very tug to the foot and sometimes can feel some pressure if the shoes are tied too tight, so keep it a bit loose. Heel feels fine with no rub or blistering. Overall, pleased with purchase.

Surprisingly goodWould have never considered this shoe but tried them on and they felt great. Didn't know about the sizing issue and am using my usual size with no issues. They're almost too short but the soft, stretchy upper and toe cap helps to avoid black toe or cramping. The mildly firm but cushioned ride is ideal for me as is the hint of forefoot flexibility. Currently using these for daily runs and tempo repeats. Very happy with this purchase and always look forward to running in them.

Kinda HeavyIt's alright. Foam is nice, the ride is good, very comfortable, it just weighs so much.

Great fit for Wider- heavier runnersI've got a slightly wider than average foot and weigh 225. These shoes are perfect for me. I started running in them in Mid October and just went through the cushioning. Most shoes last 2-3 months, but these held on for way longer. It's a great shoe for folks like me and while you do need to go a 1/2 size up, it's a solid performer.

Best Nike, in my opinionMidsole is a huge upgrade from the old react foam, I believe, with much more forgiveness and energy return. The upper seems to have MUCH higher build quality than previous iterations, which had issues with tearing in the tongue. Durability seems to be at least average, if not above average. I agree with other feedback that the fit is small, but Nike says as much up-front so it's fairly predictable. My only complaint is the weight, but for my use as an easy recovery shoe, I'm not too concerned with having a little extra weight underfoot. Overall, this is a massive upgrade from the previous version.

why are all shoes so wide and stackedI have an average to narrow foot. All shoes are being made wider today and most have a wide option. No one is making a narrow shoe (which I never had to resort to before) as all shoes were made on an average last. Now every shoe has been made wider while continuing to offer wide options. Additionally, stack heights are just ridiculous. Some of us like to feel the road. The combination of a too wide squishy maximal shoe is nothing but a recipe for an injury. This shoe is no different except that it fits slightly short which forces you to buy a shoe that fits even more sloppily.

Heel Slip or Numb ToesPerhaps my issue is largely due to my foot anatomy but I had to stop multiple times during my run to loosen the laces because my toes were going numb or tightening because of too much heel slip. Couldn’t find a sweet spot to make it work.

Just not my styleThey wore out to soon.

One major flawI don’t know why Nike thought it would be a good idea to leave excess material where the tongue connects to the inside of the shoe. It is right on top of the foot. It rubs and makes the shoe very uncomfortable
