To know the sizing for your Crocs, you can follow the steps below.
First, get any piece of paper and measure your feet from your toe to heel in CM
(centimeters).
After that, choose the model that you are planning to buy, and then check the sizing info of the respective Crocs model from below.
Crocs should not fit like other shoes. They should fit very loosely. The sides of your foot should not really touch the sides of the shoe. Your toes should never make contact with the front of the shoe. -- Crocs Malaysia
In other words, you should pick a size bigger than your normal shoes' size, to avoid unfittingly-small circumstances!
For now, I will just provide the sizing info of the models availble from Croco-Crocs.
