Economic cosplay shoes

I'm not so clear about the male's cosplay shoes.In the daily life I see them like to wear leather shoes and the gym shoes. The shoes in the above picture are the Gundam Seed.Cagalli Yula Athha cosplay shoes. It seems like the leather shoes in the daily life which made up with leather. I think that is a economic way to choose the cosplay way. Because we could wear it in any case after join in the cosplay parties when we choose this pair of shoes.
