The shoes fit like a glove, if you have them once anbekommen. The tightening is really extremely difficult for small children's feet. My son wears the shoes 22 and it fit perfectly in 22. But by its slightly higher instep and the rest of the baby fat I have to cram all already and pull until the shoes are at the foot. They fully serve their purpose, so that it runs very well and does not slip. After using I rinse them off and put them at home on the edge of the bathtub, where they dry very quickly.
