I purchased these online and have only tried them on at home, never worn them outside. The shoe size was correct, but the calf area felt a bit tight, and I'd prefer a little more room, so I'm letting them go. The seller's calf circumference was about 35cm. I tried measuring them as shown in the 6th photo, but I don't think it's very helpful, sorry. I'd like to sell them to someone who might be the right size. - Brand: AIGLE - Color: Dark Brown - Style: Rain Boots - Design Features: Leather tab with buckle - Material: Rubber Thank you for looking.
