Hi there! More than happy to help. What question are you referring to? The vendor told us that they're TTS (true-to-size). I think it's a mix of people being thrown off by the European sizing (which it doesn't correlate 1-to-1 to US sizes), but also there's folks on this thread giving honest feedback about these running big. Most brands have some discrepancies between what they say about the fit, and the feedback from users. Judging from what folks have been telling us, these run on the big side of things so if you're between sizes, please size down.
