The EU vs. US size conversion chart is partially wrong!  It does not correctly address the HALF sizes.  My US size is 6.5 and that should translate to EU 37.5.  To be safe, I bought both EU Size 37 and 38, and as expected, EU37 was too small (my toes were touching the shoe rim with regular socks) and EU38 was way, way too large (even with tick socks). Another potential problem to some is the very top of the shoes, which tends to have very little if any wiggle room.  However, I did manage to tock in my pants somehow.  Given the significant sizing issues, I am returning both pairs. Ideally, I would like the half sizes correctly addressed and for the shoes to be wider all around.  There should be no cut corners given the price of the product.
