Designers started from the ground up with this all new take on what a sandal could do and be for our community. The Auna sandal is the result of years of testing and refinement. The Auna incorporates a high rebound PU footbed coupled with an abrasion resistant forefoot strap. This sandal is built to be supportive and comfortable for long days on the water or land. It features our innovative TUFgrp outsole, a revolutionary patent pending design constructed from a specially formulated rubber compound. TUFgrp provides next level traction on flat and hard surfaces as well as wet and uneven terrain. TUFgrp is independently verified SRC rated to deliver next-level non-marking grip.
