Powerful. Aggressive. The New Balance Vazee Sigma Unisex Track Spikes Shoe in Red is in a class by itself, designed using BOA® Closure technology, an alternative to traditional laces for customized comfort and no pressure points. A midfoot canopy and heel wrap hold the spike in place. An asymmetrical eight-spike plate provides traction with just the right amount of flexibility. The Vazee Sigma features a BOA® Fit System for a locked down fit, while a powerful 8-spike plate provides traction for distances up to 400m.
