how to know if it's Italy or China

the same day I bought two pairs of red and white of the same size
and at the same price
and I was surprised because the reds are very comfortable very soft and comfortable to wear against by the white which are nevertheless well stamped fangs like red, are uncomfortable stiff the platic is rigid and irritated feet
I looked under the sole and saw that red are made italy and white china !!!
So Chinese should not meet the specifications of the composition of the original material that makes the comfort and reputation fangs !!
Crocs pity gives way to manufacture in China as if it were bad imitations and Amazon sells the same price as those that are well made with good material !!
