Hi. I am living outside the US and my mom is currently in there, so I decided to order my first Vans from their US online shop as they are pretty expensive in here. I went with the authentic gum shoe and checked Vans online size chart. My feet are 22,5 cm, usually I wear 37-38 EU size shoes. However, Vans chart told me that my measurement corresponds to US women 6, so I ordered them relying on the brand chart as there is a pretty much confusion with the Vans sizing compared to other brands. The problem is that, the shoes seem VERY small compared to normal 37-38 EU shoes (my mom compared them). I am confused with the result as I cannot try them on and Vans just doesn't accept replacement and doesn't refund the fast shipment price which is 18 dollars...

Should I return them or give them a shot once I get them? My mom is just leaving US in 2 days, so no option for buying another pair.
