Created for the waterborne operator, the Abyss is specially designed to provide exceptional traction, breathability and water release. Its slip-resistant sole unit compound has siped lugs that are made to improve traction on wet and dry surfaces. In addition, the sole features rubber technology that reduces that dreaded squeak. Supporting its dual functionality, it has side port holes that drain excess water when transitioning to land. Composed of airmesh and a double-coated synthetic urethane, the upper dries fast and is breathable. Formerly known as OTB, New Balance Tactical has definitely come up with a boot for those not afraid to get their feet wet.
