Compared with casual leather shoes, leather classic dress shoes refer to the designated styles of leather shoes that are matched with formal clothes. And when casual leather shoes are paired with a suit, it is generally a semi-formal style, often without a tie.

Leather classic dress shoes are not only lace-up styles, but have their own fixed paradigms. Formal leather toes have pointed, round, square and other styles, and the heel height is medium. The colors are mainly black, brown and white. In underdeveloped countries or regions, convenient and practical lace-up slip-on shoes are often mistaken for dress shoes. In principle, leather classic dress shoes should be matched with dark socks. The length of the special suit socks reaches the calf, and no matter how big the movement is, it will not "run out" to reveal the calf.
Leather classic dress shoes, which originated from European gentleman culture, used to have strict regulations: wearing three-joint leather shoes during the day and two-joint leather shoes at night, evening dress shoes and country casual sports shoes are another paradigm. Today, this etiquette is slightly looser. First of all, two-joint leather shoes are also accepted as daytime wear. The dovetail carving style that used to be used as country casual shoes or even golf sneakers has also been included in the category of dress shoes, which is today's gentleman. They added a little randomness. Even with these changes in slack, to this day, other styles of leather shoes have not been included in the strict gentleman's formal dress code.
