Not what I'd hoped
I've been looking for some heel grips that were shaped like a narrow strip, and these were pretty close to what I wanted.  But they do NOT have any suede or leather like the description states - they are just blue foam covered in some fabric.  They are also too hard, like the foam they are made of does not have enough "give."  So, they were not comfortable at all.  The adhesive seems to be good, like they would stay attached to your shoes for a while.
