CrocsUnisex Kid's Crocband Clog T

Q: I see that a toddler size 6 is an option... Is this really a 6 or do they mean 6/7? I've never seen crocs use just one size.

bought recently such Crocs 8 size, actually size 8-9.

Q: My daughter is j4(35-36 european size) what size should i buy only gives me the option of toddler-4 i do not understand?

The size chart shows that a 35-36 is a big kid size j4. If your child is older than 5 or 6 years old than the big kid j4 should be fine. Make sure you tap on the big kid button than you can find j4. The button says big kid (8-12 years). Hopefully this helps.
