hello , I would like to buy a pair of Birkenstock Arizona shoe from you . I have they before and know my size but I do not understand you size chart . I would need Europa size 40 -lrb- 9-9 .5 US -rrb- and c-d wide or regular wide . Unfortunatelly I can see the drop down size box but can not view the right side of the drop down text . and I can not make the box larger . any suggestion ? gabi.glaezer@web.de
