Children's shoe sizing... Having a brain fart

[cjt110]

DS is 4 and a size 10. I need an 11. The website I am looking at calls a 10 "infant" and an 11 "kids" Is that the next size up?

Yes because the only other size 11 in the UK would be a large mens size.

I thought so! See... told you I was having a brain fart!

Thank you.
