I ordered these shoes online which is a bit dangerous.<br /><br />Because I have classic Irish flat feet I ordered them in 10 1/2 though I am usually either 10 1/2 or 11 depending on the shoemaker.  My feet are so flat you can't pass a sheet of paper under my arches, a condition known as broken arches.  I was thinking the smaller size would bind feet upward a bit more as is usually the case.  However, these shoes are perfectly designed.  I think I will reorder these in size 11 which should be perfect for me unless I can manhandle the pair I own.  Don't get me wrong, these are the best off the rack shoes I have ever bought as a flat-foot.  And the markings are awesome! Perfect.
