Step into Kelly Slater’s world with the Lunar. Developed by the 11x world surf champion, the Lunar is the most comfortable sandal he - and you - has ever worn. The Lunar is your everyday sandal: whether you’re heading to the beach or running errands, the Lunar will take you every step of the way in comfort and style.

Kelly wouldn’t wear just any sandal, and neither should you. The Lunar is designed with your body and the earth in mind. Meticulously crafted by our experts, the Lunar is made with sustainable BLOOM materials and developed to protect your body’s natural alignment.

The Lunar’s unique design is inspired by Kelly’s interest in the connection between turtles and the moon. The footbed mimics the moon’s surface, and the outsole reflects the turtle's 13 inner & 28 outer shell segments. With the Lunar, you don’t have to sacrifice style for comfort.    

• Made from recycled sources & BLOOM, a sustainable base made from algae. 
• Sizing is in men's sizes. 

The Most Comfortable Sandals

Made for all-day wear, experience total comfort with a thicker sole plus heel and arch support to help you take care of your body and enhance longevity.

Created by Kelly Slater

Kelly Slater is an 11x world surf champion and has been wearing sandals for over four decades, breaking records by winning the Pipeline Pro at the age of 50. After not finding the shoes that he needed, he decided to create them himself with the KLLY Sandal Collection.

Inspired by Nature

Kelly's interest in the unknown connection between turtles and the moon inspired the KLLY Sandal design. The sea turtle’s shell plates mirror the lunar cycles, which are a driving force in the ocean tides. This naturally inspired the footbed of the KLLY Sandal Collection.

Don’t buy these, they’re defective

I’m writing another review because the first pair I ordered had a defect where the strap on the right foot was a lot smaller and tighter than the left. I contacted customer support and they promptly agreed to send me another pair. I wrote my first review after that. They are indeed comfortable. However, the new pair just arrived today and they have the same problem, if not a little worse. Probably something they need to sort out in the manufacturing process. I haven’t even reached out to customer service this time because I know they probably won’t send another pair. I would expect better quality from almost $100 sandals.

Most comfortable sandals that have ever graced my feet

Seriously, I’ve never worn a more comfy sandal. Surprised by how much I love these things. 😎 🦶


Replaced my rainbows with these and I’m very happy with the purchase. I had been a rainbow flip flop wearer for about 20 years.

Solid sandal

I received a pair for Christmas. I was able to wear them on a late winter vacation to Florida. I love how they support my feet. They are thicker than any other sandal or flip-flop I own. So I never feel any rocks or pebbles like I do with thin flip-flops. Love the color, and the idea that the inspiration came from nature.


The absolute best flip flops, they have no equals
