These boots have been tried in the business so I have no problems with the size, already repeatedly described here. These boots are really great, super light and warm. Have given, because I have a high instep and boots initially expressed some only 4 stars. On top of the elastic band around the leg is a little tight for me (I have solid legs), but bearable. Vielleich are the elastic so slightly when you wear more often! I'd buy it again!
