EXCELLENT MINT CONDITION - ONE TIME WEAR - NO ORIGINAL BOX The New Balance Fresh Foam Hierro BOA is a hiking and trail shoe with a lacing system that provides a secure fit. The shoe has two dials, one for the four foot straps and one for the ankle strap, which can be popped loose and pushed down to tighten. The shoe also has a built-in sock-like ankle gaiter that blocks debris and helps snug the shoe to the foot.
