A simple model, but with a super elegant design. Havaianas Luna are everything they seem and more! But above all, they are very comfortable, with the strap at the back, so they never come off your foot. And this color will look great with any summer outfit. They are perfect for days at the beach, pool or even for everyday relaxation.

Material: Rubber
Functionality: They guarantee comfort, great durability, heat and water resistance, are non-slip and the upper part of the sole has a “rice grain” texture so that the foot does not slip.
Other information: Made in Brazil
