The sizing is a bit "off"...we got ours at Payless and here were our numbers:
Me: Normal size 6, I had to get a child size 4 in the Airwalks
DH: Normal size 11, he got Airwalks size 10
Dd15- Normal size 8, she got Airwalks size 6
Dd8- Normal size, child 13- she got Airwalks size 12
I wouldn't order online....the sizing is so far off our normal sizes...we needed to try them on at the store.
