Inspired by the needs of class V river guides. The PFD Sandal combines the secure and adjustable fit of Astrals award-winning life jackets with the Balanced Geometry and legendary G Rubber grip of our world renowned Loyak water shoes. A purpose-built Thwart Pad provides comfort while wedging under raft thwarts, and allows the PFD Sandal to be cinched tight to run, jump, swim and climb in and around the river.
