Thank you for viewing. The versatile "FuelCell Rebel," known for its lightness and responsiveness, has been updated to v5. The FuelCell midsole, incorporating PEBA and now thicker than v4, provides cushioning and also offers a bouncy response that increases with speed. The tongue structure, improved with an optimal thickness of neoprene-like material, fits the foot's movement during running in conjunction with the FANTOMFIT upper construction, assisting your feet from daily training to races. I purchased these online, but they didn't fit my foot width, so I'm selling them. I only tried them on at home once and haven't used them at all. - Brand: New Balance - Model Name: FuelCell Rebel v5 - Color: Black/White - Size: 28.5cm - Condition: New (with box and tags)
