This is the best heel I've ever bought. The heel itself is comfortable, cushioned, almost bouncy. It is more comfortable even than cork soles. The rest of the shoe is also comfortable, soft and not rigid. No blisters in my future with these guys.
I didn't wear heels on a daily basis until recently, but I've started a more professional career track and I'm always on the lookout for shoes I can wear all day and into the night without hurting my feet or my back. I've even caught myself dressing up on off days so I can wear these shoes. My mom and sister tried these on, too, and both were really surprised at how comfortable they were.
I would say that buyers might find them a little bit more narrow than expected, because I'm usually right between a normal and a wide width for shoes, and these in a wide fit me perfectly. Even if you usually buy a normal width shoe, if you have ever bought/worn a wide width in any style, I'd suggest trying the wide sizes for this style.
