Loafers
Oh man, Koreans love loafers. There is a stereotype that Asians prefer not to have laces when it comes to choosing shoes. It could be because we are lazy or because it is more comfortable. Anyway, you can see a lot of people wearing penny or tasseled loafers as their dress shoes.
Loafers are indeed comfortable during scorching summer weather in Korea, and except for the winter, people can wear this with thick socks and should still be okay. You will be able to see loafers with more younger generation people.
When it comes to loafers, it seems like people do not mind if the material is suede or leather. We see various kinds of loafers with different materials. People enjoy brands such as Dr. Martens, or Tods.
