Brown Quiksilver Flip Flops - Boys Size Size 9/10 Like new. Worn once. PLEASE NOTE: Estimating on the size as the sandal does not have any size on it. See the 3rd and 4th picture for size reference. The VANS shoe pictured is a size US 10 and looks like a match. And flip flops usually do a two size range so put 9/10 because I’d rather them be purchased and be slightly big rather than not big enough. Hope that helps!!
