All Women's Road Shoes

  • Daily TrainersDaily Trainers

    The baseline definition of a running shoe. Daily Trainers lean on time-proven designs, technologies and features for dependable cushioning, support and comfort. They're a staple in every runner's closet, and if you are new to running shoes, then you should start your journey here.

  • Performance TrainersPerformance Trainers

    Performance Trainers provide a springy feel and make longer runs easier and faster runs faster. While quicker than Daily Trainers, Performance Trainers are not nearly as fast as Super Shoes. Due to a focus on keeping things light weight, Performance Trainers are less durable than Daily Trainers. These can also be a good option for one's first race shoe.

  • Super ShoesSuper Shoes

    Super Shoes are the fastest running shoes you can buy. They are designed to race your absolute best and represent the pinnacle of running shoe technology and innovation. They have the highest energy return foams and plates for new levels of performance. Low durability, but maximum speed is the name of the game here.

    These shoes are best used for hard, rugged trails such as shale, granite or sandstone where grip on smooth surfaces and underfoot protection are important.

  • Soft & Muddy TrailsSoft & Muddy Trails

    Designed for use in muddy, soggy conditions, these shoes feature very aggressive outsoles that dig deep into soft ground for exceptional traction.

Cushioning Level

  • Cushioning level, or stack height, refers to how much shoe is between your foot and the ground. For this category, we reference the amount of cushioning below the forefoot as the heel height will be equal to or greater than the forefoot height.
    Learn more about stack heights and how we measure them.

  • Barefoot

    0-13mm. The Shoe generally does not have a midsole and feels like there is no cushioning. This shoe is all about feeling the ground underfoot.

  • Minimal

    14-18mm. The shoe has a thin midsole that allows for a natural running experience. Racing shoes and minimalist shoes are common here. These shoes offer a feeling of being connected to the road or trail.

  • Low

    19-23mm. The shoe has a slightly cushioned feel and may feature added cushioning technologies. Performance training shoes and some trail shoes are common here. These offer protection during footstrike but prioritize a lightweight, grounded experience.

  • Medium

    24-28mm. These shoes have a stack height that fall near the middle of the spectrum.The shoes in this category are verstaile and great for all types of runs and distances.

  • High

    29-34mm. The shoe has a thick midsole and ample cushioning. These shoes are highly protective and absorb more impact than the body.

  • Maximal

    35mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on protection and soft foam underfoot with hardly any ground feel.

Stability Level

  • Neutral

    Neutral shoes support the foot through a normal range of arch collapse and generally do not have a built-in technology to correct movement.

  • Stable

    Stability shoes are a great option for those who overpronate or need added support. These shoes help to limit the inward rolling motion of the ankle while running or walking and assist in guiding the foot straight through the gait cycle.


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.

How We Measure Our Shoe Specs

  • We measure every shoe in-house to provide accurate and consistent details.

  • Weight

    The weight is based on a Men's size 9 for Men's and Unisex shoes or Women's size 8 for Women's shoes. The weight listed is for a single shoe, including the laces.

  • Heel Stack

    The heel stack refers to how high your heel sits above the ground when wearing shoes. Based on Men's size 9 as the standard.

  • Forefoot Stack

    Forefoot stack refers to how high the ball of the foot sits above the ground when wearing shoes. Based on Men's size 9 as the standard.

  • Heel-toe Offset

    Heel-toe offset (drop) is the difference in height between the heel stack and the forefoot stack. We use the number given to us by the brand.

How We Measure Shoe Fit

  • All measurements are based on Medium width.

  • Fit (width) options are Narrow - Snug - Average - Roomy - Wide.

  • Sizing (length) options are Short - True - Long. Note: fit is relative to the "average" running shoe.

  • We partner with SmartLast, a program by Heeluxe, to use advanced shoe-measuring technology, to provide objective measurements for toe box, midfoot, and heel widths as well as overall length.

Interesting shoeI was intrigued by this shoe with its midsole design, the concavity on the lateral side and the aggressive arch support caught my eye. I ordered a half size up, but I think the shoe is a little too big on me. I have tried using a runners loop for the heel slip, but I didn’t notice any difference with it. Because of the heel slip, I’m not really able to run any faster than easy pace, which is fine because of the shoes weight. The weight does look bad on paper, but I can barely notice it when running. The aggressive arch support may have been a little too much for me, and I don’t know why more people aren’t talking about it, because to me it seems really unique and I’ve never tried on any pair of shoes with that aggressive of an arch. I’ve ran about 20 miles in these and they’ve treated me well, but I think once they’re done, I’ll just stick to my original trainer unless my feet grow a little more and the shoe feels better.

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.
