French-made AIGLE COUPE SAUMUR, black M size rain boots. Marked as 38. Suitable for those who wear 24 cm. (The size section cannot be changed for some reason) The inner circumference of the opening is approximately 36 cm. *Please note that these are amateur measurements, so there may be some slight errors. As this model can be used as riding boots, I think it's designed to be worn with slim pants tucked in, so the calf area should be roomy. I bought these for my daughter, but she only tried them on. - Brand: AIGLE - Model Name: COUPE SAUMUR - Size: M 38 (approx. 24 cm) - Color: Black - Country of Manufacture: France Thank you for looking.
