The size chart is designed for men, even though the advertisements are aimed at women. You need to refer to the EU sizes; their size 9 corresponds to EU 43, which is a men's size. When I commented on their ad for clarification (having previously lost $27 with another company due to a similar issue), the service did not provide an answer but instead reported my profile to the platform for 'phishing,' resulting in a 7-day suspension.
