I have the patent yoyos with the thin heel. I love the shoes and get lots of compliments, but I have had problems. By the second or third time I wore these shoes, the heel lift shifted upward into the red on the heel. By the time I wore the shoes a few more times, the heel lift was completely worn out.
I didn't do a lot of walking in these shoes, even though I work in NYC. In contrast, I have other CL styles that I have worn a lot longer before they needed a trip to the cobbler. These shoes are definitely delicate.
