Good for me
These fit well as replacements in my Saucony sneakers after a bit of side to side adjusting.  The first day my back felt the strain of having my balance corrected and I thought oh no, but very comfortable after that.  No more heel pain, which I would have rated at an 8 before.  Im on my feet 8 hrs a day and its completely gone.  Suggestion - throw out your Reef flip flops!
