Product Description
Built from the ground up for freestyle women who demand feel without sacrifice, the Union Ultra delivers a next-generation suspension system that absorbs impact, rebounds underfoot, and keeps the board talking back on every hit. Molecular cushioning floats between baseplate and topsheet like a shock-dampening layer, while the asymmetric mini disk design keeps the footprint clean and responsive. For intermediate to advanced riders who want their binding to disappear beneath their feet.
