Crocs Kids' Unisex Lined Marbled Tie Dye Clogs Size J2 Like New Worn Once...... Inside..... after I removed the tags. Truth is he tried them on ONCE...... then shoved them in the back of his closet for me to find later........ Insert eye roll. (To his credit.... we really don't need "super warm and comfortable Crocs" here in sunny Arizona, so I will give him that. :-) Apparently according to CROCS, the size is US J2 with a Heel Toe Length 8 1/8 inch or AKA Big Kids (Ages 5+). Who knew shoe sizes could be so complicated? Smoke and pet free home. Reasonable offers are always appreciated.
