At some point in the 14th C, if I remember correctly, mounted knights and nobles followed a fashion to wear poulaines or sabatons, which were really pointy shoes as part of their armor.
Unfortunately, there was a battle with the Turks, I believe, where the shoes showed the obvious drawback that you could barely stand on them, thus making it very hard to fight. Many European knights lost their lives when the enemy took advantage and the fashion came to an abrupt halt.
Couldn't find a reference to it. Wikipedia does mention those shoes re Battle of Sempach but the article didn't make the shoes seem like a big deal. Whereas my recollection was Turks, not Swiss and lots of dead knights.
