The prominent tag on the heel dug into my foot and caused a lot of discomfort the first time I wore them. Why do shoe manufacturers use those? I put in a sticky padded insole made for heels to cover the tag and now they are fine and I can wear them all day with minimal discomfort (the best I can get from just about any shoe given my sensitive feet). Note that the wedge is not cork, but is printed to look like cork.
