Nike Infinity RN4 Introduction
After I reviewed the Infinity Run 3, I stated that it was in dire want of a facelift as a result of it had the very same midsole as the primary 2 variations. Regardless of how good the experience is, 3 years of the identical factor will get boring. Midsole foams are advancing so quick and so they turn into outdated in a short time. This is the reason Nike updates the midsoles of widespread sneakers just like the Pegasus and the Vaporfly each 2 years.
The Infinity Run variations 1-3 have been impartial trainers however they felt like stability trainers as a result of poking arch sensation. After testing, I used them for informal sneakers for work, not for working. I choose my trainers to have softer, extra energetic rides. The Infinity Run felt a bit bland.
Model 4 of the Infinity Run will get the foremost overhaul that I needed final 12 months. It options Nike’s model new ReactX midsole foam which has by no means featured in a shoe earlier than. The outsole and higher have additionally been redesigned.
The InfinityRN 4 isn’t categorized by Nike as a max-cushioned coach but it surely’s priced like one. At $160, it competes with most max-cushioned trainers. The Nimbus, Glycerin, Triumph and New Steadiness 1080 are additionally priced at $160.
The burden of the InfinityRN 4 has elevated to 11.2 oz (319 g). That is a whole ounce (28 g) greater than the earlier model. Every year, the shoe will get heavier and heavier. They’ve additionally modified the identify this 12 months to the InfinityRN, which was beforehand Infinity Run.
Nike Infinity RN4 First Impressions
My first run was a 17 kilometre restoration run. It felt just like the restoration tempo was completely suited to the InfinityRN 4. The experience felt barely softer than the earlier variations but it surely nonetheless felt a bit too agency for a max-cushioned coach.
I used to be disenchanted with ReactX as a result of it felt actually just like common React foam: dense, with out a lot power return. Total, it was extra comfy than the Infinity Run 3.
The higher of the InfinityRN 4 jogged my memory of the Nike Free RN Flyknit 3.0 whereas the midsole jogged my memory of the Underneath Armour Velociti Wind.
Nike Infinity RN4 Higher
The higher of the InfinityRN 4 has a snugger match than final 12 months’s model with a softer Flyknit that’s extra stretchy. It has a slender match however continues to be true to dimension. The higher conforms to your toes and I discover it total extra comfy but it surely feels extra like a way of life sneaker.
The padded tongue is semi gusseted and it doesn’t transfer round in any respect throughout runs. Foot lockdown is superb, even with out utilizing a runner’s knot. An inner heel counter supplies heel construction and assist whereas the collar may be very well-padded so consolation across the ankles is excellent.
My least favorite factor in regards to the higher is that it runs heat. It soaks up quite a lot of sweat as nicely so it’s extra suited to chill climates. It has a brand new water repellent liner within the toe field however I didn’t get an opportunity to check it in moist circumstances.
The heel pull tab makes a return within the InfinityRN 4 which was lacking within the Infinity Run 3 however there are nonetheless no reflective parts.
Nike Infinity RN4 Sole Unit
Crucial replace to the InfinityRN 4 was an important one: the heel clip wanted to be modified as a result of it prolonged underneath the arch and prompted a poking sensation within the earlier model. Within the InfinityRN 4, they’ve eliminated the clip fully so it’s way more comfy, particularly for runners with flat toes.
I hoped for one thing like ZoomX, however ReactX is just not a enjoyable foam. It doesn’t compress a lot when loaded so it feels dense and rubbery. It doesn’t really feel energetic like ZoomX, Fuelcell, Hyper Burst Professional or Pwrrun+ and I do know that Nike might have give you one thing a lot better contemplating how a lot R&D they’ve at their disposal. This was a missed alternative in my view.
The experience of the InfinityRN 4 can’t match different max-cushioned trainers by way of cushioning and power return and the easiest way to explain the way it feels is flat. It’s the type of no-frills coach that you just simply placed on so you will get your every day mileage in. I did a 27 km long term in it and it felt actually sluggish with an outdated experience.
I solely use it for straightforward and restoration runs. This shoe doesn’t prefer to go quick. It’s heavy and it has a really versatile forefoot in contrast to the rockered MaxRoad 6 and the GlideRide 3 which assist you to choose up tempo if you’ll want to.
The InfinityRN 4 is extra suited to heel strikers than forefoot or midfoot strikers and the shoe encourages you to heel strike as a result of excessive quantity of cushioning within the rearfoot with a lot much less within the forefoot.
The phrases “supportive” and “stability” are talked about very often on the InifinityRN 4’s product web page on the Nike web site. It has a reasonably extensive midsole base with raised edges that information your toes so landings really feel decently secure however I wouldn’t classify it as a stability coach. It appears like a impartial coach.
Your complete outsole now has thick, waffle rubber protection so the midsole foam doesn’t get scuffed anymore. That is the place nearly all of the ounce of additional weight comes from.
There’s little or no outsole put on exhibiting on my pair and I believe the InfinityRN 4’s outsole can rival the Pegasus 40 by way of sturdiness. Traction is healthier than the earlier variations as a result of the lugs are raised and the outsole is not fully flat.
Nike Infinity RN4 Conclusions
After the first run, I didn’t stay up for working within the InfinityRN 4. Although it has been fully redesigned, it nonetheless lacks pleasure. The brand new midsole doesn’t present sufficient power return and it doesn’t have a novel experience. ReactX doesn’t really feel like a new-age midsole foam and it must be a lot softer.
InfinityRN 4 is the most effective model to this point within the collection as a result of it has probably the most comfy higher and is arch pleasant, nonetheless it’s disappointing that it has picked up an oz. of weight. It appears like a heavy shoe throughout runs as a result of there isn’t a outstanding rocker to make transitions extra environment friendly.
The InfinityRN 4 is a median working shoe with no main flaws however at $160, I can’t suggest it when there are a lot better max-cushioned choices, just like the Skechers MaxRoad 6 which is simply $130. The MaxRoad 6 has extra cushioning, a softer experience, and way more power return.
In some ways, the InfinityRN 4 appears like Nike’s model of the Ultraboost Gentle: a way of life coach which it’s also possible to use for the occasional run. They each have knitted uppers, agency rides and are overpriced.
