Uggs are comfy and warm and Crocs are comfy and cool. I was in Israel this summer and every single person had them, parent, child, you name it- the little ones are kind of cute actually. Every single store had them, with different colors, differnt color replacable
straps, little decorative pieces that you snap into the little holes on top of the shoe..
This picture here was from an outdoorsy/hiking type store. Just a small piece of their selection!
They're really good for the Israeli lifestyle/climate, so they probably won't go out of style there anytime soon. I mean, people there are still wearing those giant chunky platform sneakers (and not with just the foam sole either- the hardcore rubber rounded soles.
Everyone in my high school had Uggs. Maybe the fact that everyone wore them made it okay that they were ugly? They actually came out with some nicer looking ones with a different silhouette and different colors though.
EDIT: The crocs are also more expensive in Israel- about 250 shekel, I *think*... which would be about 55$ (!!)
