Spec analysis — not yet tested
What this page is. A podiatrist’s reading of the manufacturer’s published specifications for the New Balance Fresh Foam X 880v15. Nothing on this page has been measured, worn or scored by us yet. There is no score and no seal here on purpose: under our standard, a number only appears once a pair has been on the bench and on the road. When this shoe is tested, this page is replaced by the full review and the change is logged.
The 880 is New Balance’s everyday neutral trainer, the shoe most of its running-store fittings start from. Version 15 raised the stack and cut the drop to 6 mm, which changes who it suits. Here is what the published figures say, what a foot and ankle surgeon reads into them, and what we will measure when the pair reaches the bench.
What New Balance says the Fresh Foam X 880v15 is
New Balance lists the 880v15 as a neutral shoe, “Best for Everyday Running, Long Runs”, built on its Fresh Foam X midsole (which the brand says contains about 3% bio-based content) with a “structured yet breathable engineered mesh” upper. It is one of the few running shoes still sold in four men’s widths (B, D, 2E, 4E) and four women’s widths (2A, B, D, 2E), and both the men’s and women’s pages state that the shoe “Received the Seal of Acceptance from the American Podiatric Medical Association”. Price is $149.99 either way.
Manufacturer specifications
Source column tells you where each figure comes from. “New Balance” means the brand’s own US product page. A retailer name means the brand does not publish that figure and a retailer does. “Not published” means nobody reliable does — those are the figures our bench measures first.

What the spec sheet suggests — and what only a test can answer
The drop went from 8 mm to 6 mm. Two millimetres sounds trivial. For a heel that is fine it is. For an irritable Achilles tendon or a plantar fascia that flares in the morning, a lower heel asks slightly more length of the calf–Achilles chain with every step, and some patients notice it in the first week. Runners coming from a 10–12 mm shoe should expect an adjustment period; runners already in 4–6 mm shoes will not.
The stack is now tall, but nobody agrees how tall. New Balance does not publish stack height, and the two retailers that do differ by 2.5 mm on the same shoe. That gap is exactly why this site exists: a caliper settles it. A heel in the 38–40 mm range with 6 mm of drop is a lot of foam under the heel, which usually helps heel-strike comfort and, on paper, reduces peak pressure under a sore heel — but tall stacks also raise the foot further from the ground, which can feel less stable to a patient with a wobbly ankle or peripheral neuropathy.
Four widths is the standout. A 2E and a 4E in a mainstream daily trainer is rare and is the main clinical reason to shortlist this shoe if you have a wide forefoot, a bunion, or a hammertoe that rubs. Width on a label is not the same as internal toe-box width, which we measure, but the option exists here and does not in most competitors.
What only the test can answer: the real stack and drop under load, whether the insole comes out cleanly and how much orthotic volume the shoe has, how stiff the heel counter actually is, and whether the 6 mm drop still feels like 6 mm once the foam compresses. The APMA seal tells you a panel reviewed the manufacturer’s submission; it does not tell you any of those numbers.
Who this shoe is probably for
Read from the published specification, not from wear. Treat these as hypotheses the test will confirm or overturn.
- Wide or very wide feet — the 2E and 4E options are the reason to shortlist it.
- Neutral runners and walkers who want a soft heel and are already comfortable at 6 mm or less.
- People replacing an 880v14 who are happy to accept a taller, softer shoe.
- Achilles tendinopathy or a morning-stiff plantar fascia — the lower drop may need a heel lift until we measure it.
- You need a stable base (ankle instability, neuropathy, balance concerns) — a tall soft stack is not automatically your friend.
- You run custom orthotics — insole removability and volume are unpublished; wait for the OVR.
What changed from the previous version
New Balance does not publish a changelog. Fleet Feet’s review of the v15 reports a substantially taller stack than the v14 (roughly 29/21 mm to about 40/34 mm heel/forefoot), the drop cut from 8 mm to 6 mm, a small weight increase, a snugger midfoot, and an outsole pattern that changed from diagonal to vertical lugs in the forefoot. Treat those as retailer figures until we have both versions on the bench. An 880v16 has been rumoured on speculative sites but is not listed on newbalance.com as of September 6, 2026 and has no coverage from established reviewers, so we treat it as unconfirmed.

Questions people ask about the Fresh Foam X 880v15
Is the New Balance 880v15 a stability shoe?
No. New Balance lists it as neutral. Its stability sibling is the 860v15, which adds what New Balance calls a Stability Plane and is about an ounce heavier.
What is the drop of the 880v15?
6 mm, per New Balance. The previous version was 8 mm.
Does the 880v15 come in wide?
Yes — men’s in D, 2E and 4E (plus B), women’s in 2A, B, D and 2E, per newbalance.com.
Is the 880v15 good for plantar fasciitis?
On paper it has a lot of heel cushioning, which many heel-pain patients like, but the 6 mm drop is lower than the 8–12 mm most heel-pain protocols start from. We will not call it either way until it has been measured and worn; that is what the seal is for.
What happens next
This model is in the queue for bench testing under Standard v1.0: weight on our scale at men’s US 10, heel and forefoot stack with calipers, internal toe-box width and depth, torsional rigidity, heel-counter stiffness and an Orthotic Volume Rating with a real orthotic inside it. If it goes on to wear testing, the nine-criterion scorecard and the seal decision follow. Every number will carry its own provenance label so you can see which figures we measured and which we are still quoting. If you own a pair and something on this page contradicts what is on your feet, tell us — corrections are logged.
