I ordered these for my dad, he wears 7W in US men sizing... according to the description a 41EU should be the equivalent to a 7-7.5US, yet these shoes were like an inch larger! they were a perfect fit to my husband, who wears 8.5US... I want to order them again, but Im really confused on the sizing...where can I confirm the correct size to order? The information on the sizing guide cant be correct, or I was sent a deffectiive pair...
