I just gave it to my grandson a few days ago when I arrived in Israel.  He loved it right away but the weather was too beautiful in Israel to wear until today, which was rainy and he wore it for the first time.  He was looking forward to wearing them and looked great in it and will probably be able to wear it for close to a year because he generally wears a 10 or 10 1/2 shoe so I bought the size 11.  It was roomy enough without his foot slipping out. Since today is the first time he wore them I really don't know how they'll hold up, but I'm hopeful.
