FuelCell Sigma SD-X 'White Black'

The New Balance FuelCell Sigma SD-X ‘White Black’ showcases a simple two-tone finish on a performance track spike made for 60m to 400m races. The seamless white knit upper features traditional lace-closure and a sock-like elastic collar. Oversized NB branding sweeps across the lateral forefoot. The lightweight, airy build rides on a FuelCell foam midsole, enhanced with a full-length carbon fiber plate for added responsiveness. Underfoot, the contrasting black outsole uses built-in pins to deliver explosive acceleration.
