Quite comfortable although the straps are large even with the buckles.  Luckily they aren't necessary to have tight to wear these sandals.  I wore them for 3 or 4 hours and totally forgot I was wearing new sandals/shoes until my mom asked if they were new.  I showed them off proudly even though my mom's eyes were a bit large even as she said how nice they looked.  LOL  Lots of strappy-ness.  Comfortable even on my 63 year old feet.  Its nice they are flat, no wobbling as you walk.
