If you’ve spent any time looking for a sneaker that doesn't look like a bulky, neon-colored brick, you’ve probably seen the New Balance DynaSoft Nergize v3. It’s everywhere. Nordstrom Rack, Amazon, the gym, your aunt’s closet.
But there’s a bit of a misunderstanding about what this shoe actually is. Is it a runner? A trainer? A slip-on for grocery runs? Honestly, it’s a bit of everything, which is exactly why people buy it. It’s the "Swiss Army Knife" of shoes, but it has some quirks you should know before you drop your cash.

The DynaSoft Nergize v3 Breakdown: What’s Under the Hood?
Let’s get the tech specs out of the way. The "DynaSoft" in the name refers to the midsole foam. New Balance claims it has about 3% bio-based content—which is a nice nod to sustainability—but the real win is the responsiveness. Unlike the marshmallow-soft "Fresh Foam" line, DynaSoft feels a bit more "springy." It’s firm enough that you don't sink, but soft enough to handle 10,000 steps without your arches screaming.
The upper is a mix of synthetic materials and a heathered mesh. It’s incredibly breathable. If you’re the type of person whose feet get hot the second you start moving, this is a lifesaver.
The Weird Lacing Situation
One thing that confuses people is the construction. It’s a bootie design. Basically, the tongue is attached to the rest of the shoe. It’s one solid piece. You can tie the laces, but they're almost decorative.
You’ve got a gore band (that’s a fancy word for an elastic strap) that wraps over the midfoot. This gives you a "locked-in" feel even if your laces are a bit loose. It’s great for people who hate faffing about with double knots. You just slide them on.
Is It Actually Good for Working Out?
This is where things get nuanced. If you’re training for a marathon, stop right here. These are not long-distance running shoes. The New Balance DynaSoft Nergize v3 has a 6mm drop, which is relatively low. It doesn't have the heavy-duty stability or the massive stack height needed for high-impact road running.

However, for a HIIT class? Perfect.
Because they’re so lightweight—we’re talking about 173 grams (6.1 oz)—you feel fast on your feet. The low profile gives you a better "ground feel" than a platform sneaker. That’s a massive plus for lifting weights or doing lateral movements in a Zumba class. You won't feel like you’re going to roll your ankle because you're sitting closer to the floor.
Real Talk on Comfort
The memory foam insert (NB Memory Sole Comfort) is the star of the show here. When you first put them on, it feels like a hug for your foot. But here is the catch: memory foam eventually compresses.
If you are a "heavy stepper" or you’re on your feet for 12-hour nursing shifts, you might find that the initial "cloud" feeling fades after a few months. Some users on Reddit have noted that while the shoe fits true to size, the heel is a bit low. If you try to swap in a thick orthotic, your foot might pop out of the back. Stick to the original insole if you can.
Why Travelers Are Obsessed With This Shoe
Go to any travel forum like r/HerOneBag and you’ll see the Nergize v3 mentioned constantly. Why? Because they weigh almost nothing and they squish down flat. You can shove these into a backpack side pocket and they won't take up any room.
They’re also "stealthy."
A lot of athletic shoes look... well, very athletic. The Nergize has a sleeker, more tapered toe box. In the all-black or "steel" colorway, you can wear them with jeans or even a casual skirt, and you won't look like you just walked off a treadmill. It’s the ultimate "one shoe for the whole trip" candidate.
Comparing the v3 to the v2: What Changed?
If you have the old v2 and you’re wondering if it’s worth the upgrade, the answer is usually yes.
- The Foam: The v3 feels slightly more substantial. The v2 was almost too thin for some people.
- The Grip: New Balance added more rubber in high-traction areas on the outsole of the v3. The v2 could get a bit slippery on wet pavement; the v3 handles it much better.
- The Aesthetic: The v3 looks a bit more "premium." The materials feel less like plastic and more like a performance textile.
Actionable Tips for Potential Buyers
If you’re ready to grab a pair, keep these three things in mind to avoid a return shipment:
- Check Your Width: These shoes tend to run a bit narrow. If you have wide feet, definitely look for the "Wide" (D) width option. The "Standard" (B) width is quite snug because of that bootie construction.
- The "No-Sock" Rule: You can wear these without socks because the interior is smooth, but the mesh is thin. If it's 30°F outside, your toes will freeze. These are definitely 3-season shoes.
- Size Up? If you are between sizes (like an 8 and an 8.5), go with the 8.5. The stretchy upper is forgiving, but the length is pretty exact.
The New Balance DynaSoft Nergize v3 isn't trying to be a technical masterpiece. It’s a lightweight, stylish, and incredibly convenient "life" shoe. Whether you're rushing through TSA or finishing a set of squats, it just works. Just don't try to run a 10k in them—your shins will thank you.
To get the most life out of them, avoid the temptation to throw them in the washing machine. The heat can break down the DynaSoft foam and the glue on the gore band. Instead, use a damp cloth with a bit of mild soap for the mesh. Let them air dry away from direct heat to keep that memory foam from hardening.
