More comfortable than flats!
Size: 8.5, Color: Bay Fog
I love these sandals! They run true to size, and they’re sooo comfortable. I was worried about getting fakes, but these were the real deal. The color is lovely (light purple). The foot bed can get dirty, but I find them to wash up nicely (by hand, not machine). I have purchased two more colors since! So much better than flats!

Comfy dual-mode sandals
Cute, quite comfy to walk in and love the support of the heel strap! It is not as comfy if using in slipper mode because the straps don’t keep your foot tight enough. I am usually a 8.5 but it runs slightly small so I switched up to a 9.

Love them
Size: 5.5, Color: Red Pepper
I have gotten so many compliments on these shoes! They’re true to size and comfortable. Because of the material feet might sweat easier if hot but they dry quick. Quality is great and the color looks good, it’s more of a orange/red color. I got a 5.5 size
