A flip-flop with support features usually reserved for much more substantial footwear the Chaco Flip thong cradles the foot for all-day comfort. You still get the relaxed airy feel of a flip-flop but instead of a flat slab of unsupportive rubber underfoot you get the Chaco Flip's BioCentric™ polyurethane footbed to encourage a biomechanically correct stride. The flexible polyurethane is lighter than previous versions and offers greater durability than the EVA used on competitive products. For superior traction poolside or atop a boulder the Chaco Flip thong boasts a non-marking Vibram® outsole yet another feature that sets it apart from the crowded flip-flop market.
