Just wanted to give a review on the Forever21 peeptoe slingbacks that I found last week. They are similar to the pic below, but they have a wicker/straw covered heel and platform. I get lots of compliments on them but they are UNCOMFORTABLE! I am usually able to walk in high heels. I would say these are about 4 1/2" inches. They hurt if standing for more than 20 minutes. I wore them to a baby shower on Sunday and totally regretted it. After walking a bit, they also pinched in the front where the peeptoe was.
In the realm of shoes you get what you pay for. These were about $20, so I didn't expect them to be very great. Overall, they are cute looking and the nude is very versatile. You just have to wear them on a day when you know you won't be standing/walking/going up stairs very much. I also found them to be pretty true to size. I am usually an 8, and I took an 8 in these. Hope that helps!
