Shipping took a while longer then expected. These rain boots are my first pair of crocs. I was told they run big. I am a size 7 1/2 I ordered a 7. I feel they are bulky and very wide In The foot area but I think if I ordered a 6 I would not be able to put on or take off boot. I kinda feel I'm in moon boots, not as sleek as other rain boots look. Yet the boot is very light weight It's going to take time to wear them in, just like any croc. Like other reviews ab the calf area. I have smaller calves so I have room.
