Men's Reef Santa Ana Flip-Flops A favorite REEF sandal, the Santa Ana makes you feel good just saying its name. And it looks even better - not the palm frond-inspired side wall. Right? But most of all, slip into it and feel the cushiony softness with high arch support, a padded vegan leather strap, and bamboo-inspired texture under foot for a no-slip grip. You get all the feels with this water-friendly Santa Ana.
