I've been a little disappointed in these shoes - and I really expected to love them.  While the shoe is cute, the foot bed hasn't been horribly comfortable in my opinion.  I thought these would do well for everyday wear, light walking, running errands - but I find my feet hurting much sooner than I'd expect.  Costco is a large store, but not so large that I would expect my feet to be hurting before making it through the store.  I also assumed that the tab on the back of the shoe was to help pull the shoe since there is no loosening of laces to make it easier to slip your foot in, however, the first time I pulled on the loop, it tore off.
I'll continue to wear these, but will try to make sure it won't be days with lots of walking and may try slipping an insole in to see if it helps any.  Was really hoping they'd be more versatile and stand up to decent amount of walking.
