I bought these shoes to wear to my husband's company "winter party," a cruise on the bay held in January (brrrr!).  It was the first time I'd worn these shoes and the only place we could find to park was a fenced lot about a block away from the pier.  The pumps were comfortable from the time I put them on.  The lot we parked in closed at 11:00 p.m. and the party boat got back into dock at 10:55.  Like Cinderella, I had to run to my coach before it turned into a pumpkin (or in this case got locked in for the night, leaving us stuck in another city, an hour from home).  I ran about half a block in my heels and they performed admirably.  We got to our car in time, the shoes held up and I didn't get a single blister.  Oh, and they're very pretty, too.  I own two other pairs of Vaneli shoes, purchased five years ago, and they're still in great shape.  I highly recommend them.
