New Balance FuelCell sneakers with a lightweight and breathable upper. - Brand: New Balance - Model Name: FuelCell - Color: Black - Features: Lightweight and breathable upper - Sole Type: Cushioned sole Thank you for viewing. The following is quoted from the official website: A new color has been released for the "FuelCell Propel v4," a shoe with a plate that combines stability and responsiveness. The softer FuelCell midsole than before, combined with a TPU plate that is more flexible than a carbon plate, reduces the burden on the body while providing responsiveness and ensuring stability. You can feel the smooth forward propulsion, making it an excellent entry-level model with excellent control, perfect for beginners and training. I purchased these a year ago and have used them about 5 times. I am selling them because I am pregnant and will not be using them.
