@ divorce guy: Read the "surprise gift" part before responding "tell him to go to adidas" unless you don't know what "gift" means. Just for sake all of my frens and people i know including myself send clothes, shoes or anything as a gift if any of our known person is going to Nepal from US.

@Sambhabi: Nepal uses Euro and UK numbering System for shoes. US size of 8.5 is equivalent to UK size 8 or EU size 42.
