I don't know what they were thinking when they designed this nimbus 19 but your toes get squeezed it is so narrow at the top of the shoe!  Im accustomed to ordering a full-size up when I butly ASICS but this but this was ridiculous.  I have a narrow foot so its not like I am unusually wide at the top of my foot! I don't see how anyone can wear the shoes.  To make matters worse even though Im a prime member apparently Im being charge for return shipping  Not happy at all
