“Size conversion is wrong”

“Arche shoes beautifully combine comfort, style, and sophistication. This particular shoe was shown in the Sierra catalog in US sizes only. I ordered a 6.5, as usual. But the shoes came in a box marked BOTH 6.5 (US) and 37.5 (Euro). These are not the same sizes! A 37.5 Euro is a 7 US, not a 6.5 US. And, the shoes do not fit. I beg Sierra Trading to list BOTH sizes shown on any Arche boxes so those of us who know how the line fits us can make an informed choice rather than a costly return.”
