When ordering then size 42 ordered because a different size unit could not be selected as "42".
Result: much too large.
In Germany: The does not fit! 42 true, but in Chucks I 7!
On the packaging: EUR 42 MENS WOMENS 10.5 8.5 8.5 UNISEX
Would the size units are specified in, for example, with UNISEX, then that would have certainly helped. On each Chuck sole is the size - but not in EUR!
