BRAND NEW SUSINA BRYNLEE 👟SLIP-ON’S👟Size 8 ½ M

bought these while on vacation and I didn’t get a chance to return them as I tried them on in the store but when I got home they were a little too small. They say a size 8.5 but more like a size 7.5 -8. I’m just trying to get back at least some of what I paid for them which was $39 on sale At Nordstrom’s.
