I have a couple colors of the Target Merona Esma sandals and they are on sale for like $10. I have a couple expensive pairs of sandals but I have been preferring these lately! Target also has a couple other similar ones for $12 which I like a lot too.
I love Born sandals too! Although sometimes I feel like Born stuff is a little geriatric looking (like a lot of comfy shoes!), I feel like they are well suited for my flat feet and much better for me than flip flops.
