## Product: New Balance FuelCell 990 V6
**Brand:** New Balance

## Pros
- Exceptional comfort right out of the box and after extended use, with many reviewers noting they feel significantly better than other running shoes they've tried
- Excellent material quality and superior construction throughout the shoe, with structural integrity maintained even after months of heavy daily wear
- Ideal balance of cushioning and sole firmness—the FuelCell foam provides responsive support without being overly soft
- Minimal heel-to-forefoot drop creates a natural, grounded feel that avoids the awkward downhill sensation of higher-drop shoes
- Effectively alleviates foot pain, with reviewers reporting relief from plantar fasciitis within a month of regular wear
- Outstanding fit and versatility—works equally well for casual wear, all-day comfort, and active use
- Lightweight design paired with excellent stability and reliable performance across multiple pairs
- Requires minimal breaking-in, achieving full comfort within just a couple of days
- Made in the USA with 70% domestic value, appealing to those who prioritize American manufacturing

## Cons
- Midsole softens and becomes spongy over time, reducing the firmness and stability that made earlier v5 versions superior for long-term support
- FuelCell foam redesign prioritizes softness over the firm platform that long-time 990 users prefer, resulting in reduced ground feedback and resilience after extended use
- Sizing runs large—most reviewers recommend ordering a half to full size down, which adds friction to the buying process
- Insoles are surprisingly minimal and may require replacement to achieve optimal comfort and support
- Not ideal for those with balance issues or peripheral neuropathy, given the reduced firmness compared to previous versions
- Better suited for casual wear than for those who need maximum stability and support during rigorous activities

## Bottom Line

The 990v6 is an exceptionally comfortable shoe that excels at everyday wear and provides genuine relief for common foot issues like plantar fasciitis. However, if you're a longtime 990 devotee who valued the firm, stable platform of the v5, you'll likely notice the softer FuelCell foam feels like a step backward—the midsole loses resilience over time, and the shoe trades stability for plush cushioning. Be prepared to size down by about a full size, and keep in mind this is better suited for casual, everyday wear rather than serious athletic pursuits. If maximum long-term stability and support are priorities, you might want to consider whether the v5 remains the better choice for your needs.
