I find these shoes to fit true to size (at least on my size 10 feet) and to be very comfortable. I did not have the previous reviewer's problem with toe-cleavage. The round toe is extremely comfortable.

I'll say this for Naughty Monkey; I'm great at the act of walking in heels, but if there's a slick bottom, anybody'll fall flat on their butt sooner or later. Naughty Monkey has a super grippy bottom on the front of their shoe, and their shoes come with replacements for the rubber at the bottom of the spike.

If you want a fun pair of comfortable shoes, these are fantastic. my only complaintis that the red is not nearly as red as in the picture, but the green and red are true to colour.
