The boots are very high quality, have comfortable heel height. On the bottom, soft, comfortable, but the higher, the more closely. The Vario shaft can be adjusted within a range, but that's hardly anything. Most calves are widest not just below the knee. I have information on the Calf width greatly missed and have it remeasured in size 38.5: widest point just measured a hand width below the rim - 17.5 cm.Bei my calf circumference of 36 cm, they were too tight. One has to say that the shaft is lined with a foam-like food, which is very advantageous in the winter, but still exrta Vollumen approved test boots like me, I can not bear unfortunately. Delivery fast.
