New pair or stiletto heels ?

Brand new pair of these gorgeous heels, gold platformy bottom with very high stiletto heel, tie up round leg.. bought in spain what the man said were a 7 (maybe they are, but a small 7 in that case) they have size 39 on bottom so i would say they are a 6 as my shoe size is 7 and they are a tad too small. They are very glamourus and cost me 50 euros :( and are too small and cant take them back (obviously) the brand is falala and they have gold heel and sole and then silk material across toes and ties up for leg black and bit of red and green leaf/ flower like desigm printed on them. with gold and diamonté buckel type thing in the middle. see the photos to collect from chatham kent
