Please take note of the two bluchers, the derbies on the right and the boot in the middle. With bluchers, the laces are tied to two separate pieces of leather attached to the vamp. Because of this construction, the blucher gives off a more casual feel than the oxford, which itself has a slit in the vamp where laces are to be tied. Therefore, the blucher should be laced up in a more casual manner.
Notice anything weird about them? In a word, FAIL. Bluchers are to be laced “open,” in a crisscrossing pattern, the same way you would lace up sneakers. Oxfords are to be laced “closed,” or flat across, as (incorrectly) pictured above.
Gilt MANual published an excellent article regarding how one should tie bluchers vs. oxfords, but the link seems to be down at the moment.
