Blue Sidas sports sandals, size 38/39, made of synthetic material. - Brand: Sidas - Size: 38/39 - Color: Blue - Style: Sports sandals - Material: Synthetic material Thank you for looking. Although it says 24 cm, they are a bit large. They should fit perfectly for those who wear 24.5 or 25 cm. I haven't worn them much because the size didn't fit. They have been washed at home. I think you can still wear them plenty. Please consider them if you don't mind.
