In Japanese, there's a well-known saying that goes: おしゃれは足元から (oshare wa ashimoto kara) with the literal meaning of "Every good outfit starts with the shoes" -- or as we often put it in English, "Shoes complete the outfit".
This saying drums home the importance of investing in good footwear, first and foremost: When putting together an outfit, be sure to start from the shoes up, as shoes generally make the loudest statement. You may wear a fancy suit, but if your shoes are not up to scratch or simply not polished, they can all too easily ruin your otherwise perfect look.
Even a cursory glance at all these titles showing up on YouTube will tell you how commonly the saying is used.
