No arch support in the shoe themselves, there is a bit in the removable insole provided but when it is removed it's virtually flat. These shoes are NOT leather aside from a tiny strip for decoration (this seems to be a trend with shoes lately so they can tack on the word 'leather' in their descriptions).  Laces do not lock at any point so if you are a real hiker this will be annoying and over long term unusable. There is very little padding in the footbed aside from the thin insole, the sole seems sturdy with quite a bit of shock absorption so this is probably the best thing about the shoes aside from the overall look.
