I have wide, flat, pancake-like feet. The arch support in these shoes made my feet tired and I considered sending them back. I discovered, though, that the footbed flattened to fit my feet after several hours wear and they are quite comfortable now.

FYI: if the elastic ties are too long, you can adjust them. The plastic dongle that holds them is actually two pieces that you can pry apart. Take them off, cut the elastic to size, and put the dongle thing back in place. It may take some patience, depending on how nimble your fingers are. :)
