These are WIDE, so they're recommended for those who wear 23cm shoes! The retail price is high, so please give them a try(*´꒳`*) I've only used these indoors for a few months! The inside of the right shoe has a crease/wear mark that's almost worn through. You could sew it or patch it up, and it wouldn't be noticeable⭐︎ They're for running, and marathon runners also use them! I was told they're shoes that don't make you tired even after 8-10 hours of standing work! I wore them in rotation, so they're in good condition⭐︎
