The boots are really extremely light - I have weighed for fun times, both together just 190 g! Other pairs of boots of this size weigh loose half times ... No poorly made seams or "welds", also inside especially, all seems well. The lining (black with red, plush envelope) is removable, reinforced sole in the envelope with elastic. The length of the insole (= feed) is 16 cm, the width on average 6 cm. Profile of the boot sole is ok. The shaft has no lining a circumference of 25.5 cm, which is quite far. My daughter has just as the Gr. 24 achieved, these boots are however still very abundant. But the next growth spurt is determined yes ...;) I can About the runnability in any case not yet reported, or if you get cold feet, but the latter, for example, I do not think so.
