Short answer
The New Balance FuelCell 990v6 marks a dramatic performance-driven evolution in the historic 990 series. Real-world user reviews indicate that the 990v6 features an exceptionally long toe box and a narrower midfoot profile, making heel slippage a common concern for standard-width wearers who stay true to size (TTS).

Fit Notes
- Nike Dunk Low / Air Force 1
- Standard Nike lifestyle shoes feature a flatter, truer-to-size length profile. Staying with a US 10.0 in the 990v6 results in excess toe-box space and heel slippage. Sizing down 0.5 in the 990v6 provides a secure, snug fit that aligns well with the foot's natural shape.
- New Balance 993
- The 993 features a wider, more accommodating forefoot and a truer-to-size length. The 990v6 is physically longer and narrower. Standard-width wearers must go down 0.5 size in the 990v6 to match the length of the 993, while wide-footed individuals may require a wide option to ensure proper width without sizing up in length.
- New Balance 990v5
- The 990v5 utilizes a traditional, roomier upper. The 990v6 is narrower and runs significantly longer, requiring standard-width 990v5 wearers to size down 0.5 in the v6 to maintain a comparable, secure heel lock and avoid dead space in the forefoot.
- New Balance 2002R / 9060
- Both the 2002R and 9060 feature a tighter, more compact interior chamber. Staying true-to-size in the 990v6 feels loose and long compared to the snug fit of the 2002R or 9060, making a half-size reduction the standard recommendation to align the length appropriately.
Sizing FAQ
Does the New Balance FuelCell 990v6 run true to size?
Generally, no. The New Balance FuelCell 990v6 runs long, typically approximately 0.5 to 1.0 centimeter longer than standard running shoes or previous 990 iterations. Narrow to standard-width individuals should size down 0.5 from their typical true-to-size measurement to eliminate excess toe-box dead space and prevent heel slippage. However, individuals with high insteps should stay true-to-size to avoid painful seam clamping at the tongue, and buyers of limited-edition collaboration models should also stay true-to-size as they are built on a shorter, modified last.
Is the New Balance FuelCell 990v6 good for wide feet?
Yes, but wide-footed individuals need to carefully manage the relationship between length and width. The standard D-width of the 990v6 is narrower and more tapered than its predecessors. Instead of buying true-to-size (which creates too much length and heel slip), the most effective strategy for wide feet is to size down 0.5 and choose a Wide (2E) or Extra Wide (4E) option. This clears out the excess length while providing optimal lateral room to prevent the pinky toe from pinching.
How is the arch support on the New Balance FuelCell 990v6?
The 990v6 provides solid medial stability and arch support using a firm, dual-density ENCAP rim that wraps around the rearfoot. This setup effectively resists overpronation and supports flat arches. However, because the last is built on a curved contour, proper size alignment is crucial. If you wear a size that is too long and your foot slips forward, the built-in arch support will misalign with your foot's natural arch, creating an uncomfortable feeling of unevenness under the midfoot.
