J Crew toddler boy fish flip flops. Navy foam base with canvas like green fish toe straps. Unsure of the size. Heel to toe full length measures 7.25" My little guy outgrew them around 3 years old. I'd guess these would fit a US boys size 7-8. I could be wrong, would definitely reference the 7.25" length measurement for best fit. They have some wear on the bottom but have a lot of life left.
