Developed to meet the ever-evolving demands of serious distance runners, the New Balance FuelCell collection is the perfect combo of speed, rebound and energy return. Showcasing an exciting array of cutting-edge performance-driven technologies, it promises to propel you to the next level. The core component of FuelCell running shoes is our nitrogen compound FuelCell foam technology - game changing midsole cushioning that delivers radically improved energy return performance. In a pair of New Balance FuelCell running shoes, you’ll feel the benefits with every propulsive stride. After manually manipulating the upper to relieve this discomfort, I set out on my first run in the shoes and was pleased to discover how light yet responsive they were.

The midsole becomes slightly more rigid in the midfoot and heel where the foot is less flexible. New Balance’s Response performance insole rests on top of the midsole to further enhance the shoe’s responsive and supple feel. The slip-on design is a convenient feature. It saves time when getting ready, and the snug fit ensures that they stay securely on my feet. This midsole feel works well in off-road situations where a bit more stability aids in foot control on uneven terrain. On the tarmac, however, the Dynasoft foam was not forgiving and was especially noticeable while testing on concrete floors over multiple hours. If one limits his or her use to a few hours per outing with this shoe it will wear properly. The Fuelcore midsole employs a combination of EVA foam densities to achieve the optimal balance between responsiveness and softness. It's a wrap! And it feels good on the foot. I especially enjoyed the height of the upper surrounding the ankle which offered great support on the trails and reduced the potential for rolling ankles where the terrain got loose.The innovative mesh upper provides plenty of ventilation. The engineered mesh construction promotes ventilation for increased breathability while remaining durable enough to withstand daily wear on any surface thanks to the extra forefoot reinforcement among other features. Midsole Each one of our New Balance FuelCell running shoes in the range offers subtly distinct performance characteristics, allowing you to select a model that perfectly matches your running style and goals. For a comfortable, well-cushioned ride – look no further than the New Balance rebel v2 (FuelCell), up for training runs and intense runs alike. Every piece has its iterations. Adding to the collection came with careful consideration, if it wasn’t adding to the racing experience then it had no place. Step forward the FuelCell SC Elite v3, it complements the midsole’s super springy rebounds with the dynamic energy return and stability of our Energy Arc system and a full-length carbon plate. Every aspect of its design is developed to deliver PB-busting race day speed. Meanwhile, the New Balance FuelCell Propel v3 offers exceptional day-to-day performance courtesy of lightweight uppers. If you’re after a versatile all-purpose runner that’s allows you to experience the high-rebound performance of FuellCell technology, then this is the collection for you.

Blown-rubber is strategically concentrated in an arch configuration along the toe and heel to prevent accelerated wear in these locations. However, the limited use of blown-rubber leaves the foam exposed under the forefoot.This shoe is wonderful for slow and steady training periods and anything else you want to use in your day. Given the price and quality of materials in its construction there really is nothing to complain about here. Less breathable design The comfort these sneakers provide is outstanding. The cushioning and support make them ideal for long walks, workouts, and all-day wear. I've experienced less fatigue and discomfort, even during extended periods of activity.

Upon unboxing, it’s obvious that the FuelCore Sonic is a very different-looking shoe. Without traditional laces—and the laces’ necessary accoutrements—the shoe resembles something a little more velcro-y than what we’re used to. The good news? With less “stuff”, there’s less opportunity for rubbing and chafing—super important for barefoot running and for keeping the shoe at a thrifty advertised 8.5oz weight with a small dial. The bad news? They’re not exactly fashion-forward, though to be honest, I actually did get a few compliments, so what do I know? The Fit: NB Response 2.0 Performance Insert - Provides the runner with a seamless and comfortable running experience. Since there is no tongue, tightening the laces bunches up the fabric in between the lacing eyelets were the tongue should be. This caused initial discomfort as the crinkled fabric poked and pressed into the top of my foot. New Balance Nitrel V4 is designed with a REVlite midsole to provide cushioning in the lightweight class which is very evident in your landing process. This material is also Weighing in at 6.1 oz. for women and 7.2 oz. for the men’s version, they are lightweight and agile yet still provide plenty of cushion for runs lasting up to 2 hours.The Fuelcore Coast 4 upper is flexible, breathable, and minimizes the use of seams to keep the shoe lightweight. The upper is comprised of a pliable knit material on the outside and a smooth liner on the inside. As I tightened the laces for my first run in the Fuelcore Coast 4, I noticed that the tongue was integrated into the knit upper with eyelets for the laces stitched onto the outside of the upper.

The quality of New Balance products is evident in these sneakers. They are well-made and durable, holding up to various activities and conditions.

These women's retro shoes feature year-round staples that are always a perfect fit.The New Balance Nitrel v4 is true to size with just the right amount of toe box space that did not feel restricted. Overall length was consistent with just enough room in the toe box and no slipping in the heel. The width is moderate from heel to toe without any excess room for slipping. The fit was good, but not perfect. The way the FuelCore was set up didn’t extend the laces too far down the forefoot, so the toebox was given a pretty wide berth. It worked well for me—I have a pretty wide forefoot—but it could be an issue for those with very narrow feet. I also had some early issues with my arch/knee caving inward. Clearly this is a lightweight, low-support shoe, but I’ve raced with shoes that have had the support equivalent of a flip-flop, and I’ve never had the same issue. Fortunately, the inward movement seemed to go away after a few miles, so I’m not sure if it had to do with the lateral-side BOA mounting area loosening up or just the shoe’s foam. Either way, it was fine after a few runs and didn’t cause any actual pain. The Verdict:
