Although the shoe looks good and seems well made, it is because of the central seam along the instep Unfortunately (well understood) useless for our son. The seam is inside that is not so nice and flat, as they can be seen outside, but there is a 5 mm raised bead, which you immediately feel on the foot when you put on the shoe. Possible that you could get used to it, but also possible that the bulge would cause problems even on foot in the long run.
In any case, the way how the two halves were sewn together here protruding inward in my eyes a clear faulty design and for us the reason for immediate return have been!
