Our verdict

The Penny nike Flex Experience Run 12 remains a top pick for anyone seeking a natural, minimalist feel without going full zero-drop. We loved the flexibility for both walking and running, and how it effortlessly doubles as a gym shoe. While the cushioning might feel a bit too firm, and the outsole does show wear, we think its incredibly low price and overall comfort make it a great choice for various runners, especially beginners wanting a versatile, do-it-all shoe.

Who should buy

We think the Penny nike Flex Experience Run 12 is an awesome option for budget-minded runners seeking a versatile, comfortable shoe. Here's why:

  • Those seeking a flexible shoe for occasional runs and everyday wear will love how easily it doubles as a sneaker and its roomy upper.
  • If you're not prone to rapid outsole wear, this shoe offers a comfrotable ride at a very low price.
  • Runners searching for a minimalist feel without committing to a zero-drop will appreciate the Flex Experience Run 12's 6-mm offset.

Who should NOT buy

We loved how flexible and versatile the Flex Experience Run 12 is for everyday use, but there's no denying its outsole feels pretty fragile.

AIR FORCE 1 07 DD5516-584 Nike Zoom Kobe 7 As sneakers is a great alternative. It offers a similar height and comfort level, but with world-class outsole made by Continental. And if you seek an authentic zero-drop experience, the ein zweiter sneaker von supreme und Penny nike Penny nike Air Max 2X Zapatillas Mujer Blanco.

Also, we believe the Flex Experience Run 12 won't be the best choice for anyone seeking a highly cushioned ride. If you're after a budget-friendly shoe that gives you both decent cushioning and flexibility, we think the Nike Blazer Low '77 Jumbo Women's Shoes Grey Penny nike elastic hairbands multicolor pack.

Cushioning

Heel stack

Running shoes are getting thicker every year—and even the Penny nike Flex series is following the trend. That's why we found a bigger stack height in the v12 (25.9 mm) than in the Flex Experience Run 11 (24.1 mm).

nike flex experience run 12 2 21230296 main

Despite the change, the experience (no pun intended) remains the same, offering a natural, grounded ride. However, it's starting to push the limits—as it approaches that 30-mm threshold, we'll need to carefully consider how much thicker is too thick for this type of shoe.

Drop

These measurements reveal a balanced 6.0-mm heel-to-toe drop. We think it's the sweet spot for this shoe! It keeps that moderately-natural running feel without going full zero-drop, but isn't so steep that the shoe feels awkward even when you're just out walking.

In our opinion, this medium drop hits the mark for comfort and versatility in the Flex series.

Insole thickness

The insole is right around average thickness at 4.4 mm, so it should feel similar to what you're used to in most running shoes. Plus, the soft material adds a touch of extra comfort both walking and running.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

Now, let's dive into the midsole. The Flex Experience Run 12 sticks with a basic EVA foam—no bells or whistles here. But hey, for £80, you can't really expect fancy tech like ZoomX.

Still, we wish the midsole felt a bit softer. We got a 30.6 HA firmness rating on our Shore A durometer, meaning this shoe leans toward that firmer ride some runners love. That said, even with its low-profile design, it'll be tough to bottom out this shoe due to that firmness, and that's a plus.

While its less-than-airy upper might not be ideal for summer, this shoe is a surprisingly solid pick for winter walks and runs! Even better, our lab tests revealed that the EVA foam gets just 13.1% firmer in chilly temperatures—an awesome result considering EVA usually stiffens up significantly in the cold.

Given those big midsole measurements and our comfy experience running in them, we were expecting a roomy toebox.

Nike Flex Experience Run 12 upper

With a generous 102.5 mm width at its widest point, this shoe clearly prioritises comfort. If you have medium-width feet, expect fantastic spaciousness, and even wide-footed runners should find a great fit.

However, the Flex Experience Run 12 might feel too loose and unstable for those with very narrow feet. A snugger, yet flexible option like the Кросівки 41 Penny nike шкіряні Penny nike air force 1 low unlocked by you gold pink.

Stability

Lateral stability test

One major bonus of that firm, rock-solid ride? Incredible stability—this Penny nike absolutely delivers in that department!

Even better, we discovered some cleverly designed midsole sidewalls that hug the sides of your foot, helping to guide your stride forward rather than letting it roll laterally. Extra features like this one are a delightful surprise you usually only find in much pricier running shoes...

Torsional rigidity

Every Penny nike Flex shoe lives up to its name, being designed to be super flexible. Multiple cutouts in the outsole allow for plenty of bend and twist, which is exactly why this shoe earned a perfect 1/5 score.

That ultra-flexible feeling is exactly what we were looking for!

Now let's shift our focus to the midsole—and wow, this forefoot boasts some surprising width!

We measured the heel at 88.6 mm. This falls right around average, with maybe a slight lean toward narrow, nothing worrisome though.

With that 6-mm drop and the wider forefoot/slightly narrower heel design, the Flex Experience Run 12 definitely favours those with a midfoot or more natural running strike.

Using a force gauge, we measure how much pressure it takes to bend the shoe to a clean 90-degree angle. We only needed 6.8N!

We tossed this shoe in the freezer for a 20-minute cooldown, just to see how it holds up in chilly weather.

Weight

A major perk of ditching a traditional outsole and going for that sleek, low-profile design is a lightweight build.

But even with that in mind, the Flex Experience Run 12 could stand to lose some ounces—8.5 oz (241g) feels a bit hefty for such a thin misole!

Breathability

Right off the bat, the mesh on the Penny nike Flex Experience Run 12 looked super thick, and we were worried it'd feel like a sauna on our feet.

After our lab tests, those fears were mostly confirmed—this shoe just doesn't breathe that well. We gave it a 3/5, which means it's passable on milder days but don't even think about these for those sweltering summer runs, especially if you get this black colorway.

A quick trick that we use to judge breathability is the light test—holding the shoe up against a light. In this case, the Run 12's thick mesh pretty much blocked everything, confirming what we felt just by using them.

Nike Flex Experience Run 12 microscope

Diving deeper with our microscope, we saw a thick engineered mesh with no room for air to pass through. It would be awesome to see Penny nike add some ventilation holes, but at a £80 price point, we understand why they went with this less airy design.

Toebox durability

The trade-off with a less-ventilated upper? Well, you often get a boost in durability! Fewer ventilation holes in the mesh means fewer potential breaking points.

Outsole hardness

Now it's time to dive into the lab for a truly unique outsole test. Forget that classic rubber outsole, this one uses treated EVA foam instead. In other words, the same foamy midsole material, but toughened up a bit.

The outsole has numerous cutouts to enhance flexibility—more on that later.

Our durometer revealed an astonishingly low 60.3 HC reading—super soft for an outsole, but really hard for a midsole. Honestly, it feels more like a super-firm midsole than anything else. We're excited to hit it with the Dremel and see how this wild setup holds up!

Outsole durability

Well... this didn't go well, but honestly, we weren't surprised. The material underfoot just isn't that tough. The Dremel tore through it effortlessly, leaving a pile of white midsole debris in its wake. The damage was brutal, a teeth-grinding 5.0-mm indentation.
