Track Spare Purple Blue Black Bowling Ball meta-size-chart-images Included on slide foot shoe:The Track Spare + is different than most spare bowling balls. This ball contains a performance core that will help pick up spares but will also help with strikes when you need a straighter ball. The single density i Core offers large flare potential and with the asymmetric core it provides more hitting power than the usual plastic spare ball. The Spare + not only looks good on the lane but performs like no other spare ball. Color: Purple Blue Black
