On the size of the eighth ...

... Then there is no disappointment.
As here already some other buyer is credited with the correct size selection of enormous importance.
Find 17-month-old granddaughter has currently size 20 So we ordered the shoes in size 18/19 and did well because they fit like a glove now.
The soles of the shoes are very flexible / bendable. Our granddaughter not "cost by tapping" so like a clunky Holzpantine but can flit so as if it were barefoot. Actually, she realizes not at all, she wears the shoes. In our view, a great advantage, especially for children who are running not so used in shoes.
As it turns out, the small nubs on the soles on tile beneficial - they seem to provide additional support when the child climbs out alone from the baby-pool (tested during a stay in a center Parc ;-))
At the processing of shoes there is nothing to criticize. We can talk about the durability not say much, but by the summer they will be always outgrown. And then there are just a few new ones. :-) At that price, in our view always a worthwhile purchase.
