Coming from someone who tries to avoid high heels because they're uncomfortable, these sandals were actually fairly comfortable.  It's a good size heel with good amount of front platform.  Wore this to a wedding from 3:30 - 10:30... walked several yards in cement road, grass, wood chips, walked around quite a bit outside for cocktail hour and danced for about an hour.  Surprisingly I could still walk properly by the end of the night and no blisters!
