Bought these just before a two week trip to Vietnam.  Wore them everyday (without breaking them in) and they were fabulous.  Could not believe how comfortable they were. I brought two other pair of sandals and a pair of sneakers with me because I usually like to switch it up because we do so much walking.  I ended up wearing these everyday instead.  Came back to cold weather in the US and am sad I can't wear these until it warms up.  I usually wear a size 8 or 8 1/2, bought these in an 8 and they fit great.  I highly recommend these!
