I own these in blush and in patent black. I think these shoes are exceedingly comfortable--I've worn them for hours, taken public transportation (standing) in them, danced in them... and I barely had discomfort in my feet afterwards! I go through phases of wearing heels and wearing flats, and these are still comfortable when I'm in a 'flat' phase (if that makes any sense?). The heels are low enough that your feet aren't arched into strange positions, and the material they are made from doesn't make me blister (yay!)

One note is that the shiny material that they are made from is easily scratched :( So they might show wear and tear a little faster than if you buy a pair made from the 'less shiny' material. Another note is that they don't have much traction (as with many other heels), but I attached non-slip stickers to mine and now they are perfect!
