I took 10.5 on the insole 16.5 (this is 15.5 foot + 1 cm) size is perfect, the quality is lower than average: a hard heel and a lot of glue, i think will quickly deteriorate in the process of socks, not reliable for the child.
The sandals are very beautiful, the size of the sow runs, the delivery is very fast to chelyabinsk in 14 days, the track was tracked, the seller is friendly
