Spotted these Birkenstock inspired sandals back at my local Walmart🤩 You can check out all of the options in my Reel. Their lightweight, comfy design would make them perfect for the pool or beach + the straps are adjustable! They’re only $15 and I’ve linked them below if you wanna check local stock and purchase for pickup or delivery. 

No Boundaries Women's Flatform Two Buckle Sandals Only available in whole sizes. If you're typically a half size I would go down.
