The best active flip flops I have found - they last twice as long as Sperrys - Good for boat, beach, pool, and every day wear - great rubber sole -

UPDATE - I bought these thinking they would be as good as their predecessor, the Techsun Vent Sandal, of which I had two pairs that lasted me three years. It turns out this newer model doesnt last. Ive had two pairs break in six months. The first pair broke when the front sole detached and caused me to trip and catch the front on a curb, breaking the thong part. The second pair I got smart on, and have glued parts of the sole back on 4 times, only to just have the thong break again just now.
