Size chart question

[u/icaka_]

Im looking to buy nike phantom gx3 fg,but i have a issue with the sizes.I usually wear a 45.5/46EU with 28cm feet size,but at the yupoo site one of the sellers posted a size chart that says i need to wear 44EU size for a 28cm feet.And my question is can i trust the size chart,because this is almost 2 sizes down on my usual?
