Ordered a pair of Adidas Stan Smith's in US size 5 and received a men's US size 5. Spoke to ASOS via Facebook Messenger and ASOS tried to mansplain to me the difference between US and UK sizing... Yes, I understood the difference which is why I checked your size guide AND your fit assistant. They tried to tell me that the fit assistant is not available for shoes but I provided screenshot which clearly shows otherwise. Then they told me that the fit assistant says I have a 60% chance of fitting in the size 5 so that's why my shoes don't fit. That's not the problem! Size 5 women's may have a 60% chance of fitting me but you sent me a size 5 men's which has a 0% chance of fitting me! Then they said I can send the item back within 21 days but I have to pay the $22 for postage. It would take 20 days to get this item back to the UK and I would have to incur this cost. Seriously, ASOS? I'm frustrated and disappointed. Do better.
