First of all, I definitely suggest getting these in a half size bigger, they do run a little on the small side and have a small toe box. I do find that they slip a little bit in the heel, but this does not occur often. It's not a problem for me since the shoes were a bit too small for me anyway. The heel slipping may be a problem if you buy a half size too big. The shape of the shoe is such that even heel inserts wouldn't effectively solve the problem.

These shoes were unbelievably uncomfortable when I first tried them on.

I used several methods to stretch mine out (freezing water in ziplock bags, using a blowdryer, stuffing them with socks). After about a week of perseverance, the shoes finally stretched enough for me to be able to wear them without wincing. I then wore them around the house for a couple of days.

I can now say these shoes are comfortable, especially for the height of the heel. I wear them to work, and only right towards the end of the day do I feel my pinky toe starting to hurt. The shoes are well padded, so I don't have sore feet at the end of the day.

I love the design of the shoes, they are modern and classy, and can be worn with any outfit. My only problem with these shoes now is that the sole is rounded and kind of flips up at the front, so if you tend to step on your toes first and not your heels, you will feel a little unstable as the shoe will want to roll forward. I hope this makes sense, it's not easy to describe.

Overall, definitely worth the purchase.
