New Balance FuelCell Rebel v5 "Black Castlerock" MFCXLC5
The FuelCell Rebel v5 “Black Castlerock” keeps things sharp, fast, and dependable. With a stripped-back design built for speed, this update delivers more cushioning, smoother transitions, and a subtle, no-fuss finish that works just as well on race day as it does on regular miles.
The upper feels light and breathable, using a stripped mesh that moulds to the foot without restricting movement. Reflective details sit cleanly across the black and dark grey base, adding visibility for evening runs without interrupting the sleek look. The silver ‘N’ branding carries just enough contrast to keep things visually tight.
Underfoot, New Balance has refined the FuelCell setup. The midsole uses a PEBA and EVA blend that stacks higher and stretches wider than before. It stays soft and reactive underfoot but never drags—perfect for tempo runs or those long days when comfort still matters. The outsole also gets an upgrade, adding more forefoot rubber for traction and durability.
Even the heel and tongue see improvements, with tweaks to padding that reduce bulk and increase comfort at pace. This version of the Rebel v5 feels more balanced—light on weight but steady underfoot.
The “Black Castlerock” colourway keeps the shoe grounded. It doesn’t shout for attention, but it performs like it belongs up front. Whether racking up base miles or sharpening for speed, this pair handles it without fuss. A reliable, fast option for daily training.
