The shoes were at least one full size, probably 1.5 sizes too small. I am normally a 7.5, ordered these in an 8 becuase I know ASICS run small, and they were still WAY too small. I think I would have needed at least a 9, which were unavailable in any of the color waves that I liked. I know ASICS generally size a little smaller but +1.5 shoe sizes is ridiculous. They looked nice, I got the charcoal and pinkish, but I only put one foot in for about 15 seconds before making my decision to return. Pretty disappointing.
