Can you recommend comfortable shoes for foreigners in Gangnam?

Hello! I'm a foreigner who has been living in Korea for about a year now. I'm looking for comfortable shoes to wear to school while living in Gangnam. I'm not a fan of Crocs, so I'm looking for other shoes that can cover my toes. Can you recommend any shoes that would be suitable? It would be great if I could easily find them in Gangnam or Hongdae! If anyone knows of comfortable shoes that would also look good at school, please give me some advice. Choosing shoes is harder than I thought ㅠㅠ I would really appreciate any help you can provide!
