Update. just got the 42.5 and they too seem small. Toes are still touching the ends of the shoe. Third time a charm? 43 is a full size bigger than what I normally wear being a 9 1/2 US or 42 on their charts.
Just got the shoes and am sending them back. I ordered a 42 which the chart shows is the 9 1/2 equivalent. I wear a 9 1/2 in all my shoes and the 42 is tight so I would say order a 1/2 size larger than the chart shows. Will update when I get the next pair.
