Size: Seem to be a little bit on the small size for US sizing, i will go a size larger next that what i usually buy.Durability: I walk heavy on the outside of my heals. I've never worn through a heal before these. After a season and a season and a half of ocassional wear, I'm down to the corkboard, which, surprisingly, seems to hold up better than the supersoft outsole. Speaking of which, soft outsole = scuffs. .Comfort: For short periods of time, they are heavenly. For longer periods, I miss the cushion after a few hours.
