We have now already the fourth pair Schläppchen for our son and the second pair bought as a gift for the birth. Our son wearing the shoes as slippers, because it's just like walking barefoot with warm feet is :-) The big advantage is that the shoes fit nicely at the foot, not too tight, but so that they do not slip off alone from the foot , Respect. the variables I would recommend to pay attention to the foot length, because the indication of age and the actual foot length of the child can nevertheless differ greatly. What started with 7 months directly with the size of 12-18 months and are now at 14 months in 18-24 months. Dear slightly larger buy fits as to, because otherwise, the rubber to be too tight and the foot does not fit into the shoe. Strong buy recommendation, Preis.- performance is absolutely right, fast delivery, despite the supply of the "island".
