Chart cm is approximate foot length for label matching — not a lab internal cut. Use the cm converter to map foot length across brands.
990v6 often runs slightly long versus earlier 990s and many lifestyle sneakers. Standard or narrow D feet commonly go half down to cut heel slip; wide feet should stay TTS and pick 2E/4E instead of chasing length. FuelCell plush can feel roomy day one — use width letters, not a full-size jump.

New Balance FuelCell 990v6 is a Made-in-USA lifestyle trainer with a softer stack than many earlier 990s. Independent reviews consistently note a few millimeters of extra length versus prior v5/993 habits.
Conditional advice: (1) Narrow or standard D — start half size down from your usual NB size. (2) Wide or high-instep — stay TTS and move to 2E/4E so midfoot seams do not clamp. (3) Between sizes with average width — prefer the smaller length if heel slip bothers you.
Do not confuse length with volume: sizing down a full size to chase width usually creates toe jam. Prefer official width letters.
Versus 9060 / 574 / 550: 990v6 is the plush Made line; 574 is more forgiving SL-2 lifestyle; 550 is often narrower. Use the New Balance lifestyle matrix before copying one NB size.
The RunRepeat cut on this page is US men's 9: 27.6 cm internal (276.1 mm), 94.1 mm forefoot, 67.3 mm toebox. New Balance chart cm for that same US 9 is 26.3 cm of foot length; US 10 is 27.2 cm; US 10.5 is 27.6 cm. The lab cavity at US 9 already matches the chart’s US 10.5 foot-length ticket. That is why the converter offset is −0.5 US and the fit bar sits half-big: “prefer width letters over chasing length” is the on-page lab note, not a slogan.
94.1 mm forefoot is roomy; 67.3 mm toebox is not a wide-last story by itself. D / 2E / 4E on this page are the volume tools. Standard or narrow D feet commonly half-down to cut heel slip; wide feet should stay TTS and pick 2E/4E instead of keeping extra length in a D. FuelCell plush can feel roomy day one — that is stack, not a second centimeter. Do not size down a full size to chase width; that jams the 67.3 mm toebox.
If your measured foot is 26.3 cm, chart US 9 is the length ticket; the 27.6 cm cavity is why many D-width wearers start at 8.5. Half a size on this table is 26.8 → 27.2 → 27.6 cm. Versus 550 (often D-only and narrower) or 574 (more forgiving), do not copy one NB number. There is no wear-box on this page — convert from the size that actually fits in D, then change letters before changing length.
