I found this Crocs super cuddly and comfortable .... really nothing to complain about, I could perceive no plastic smell. BUT: there are any shoe size twice. Once combined with the larger number such as 37/38 and even with the smaller number eg 36/37. Just my size - namely 40 is only available as 39/40. So I've just tentatively ordered this. They were too small for me :-( and the next number 41/42 is me unfortunately already too big. Too bad! I would really like to keep those shoes. So I had to send them back. Shipping & Return Shipping - as always with Amazon - everything was perfect!
