So I am definitely late to the BzzAgent game... I signed up a few months ago and have joined only a handful of campaigns. My very first BzzCampaign was the Dr. Scholl's High Heel insoles - I still have a whole bunch of high value coupons for these!
I personally have yet to find a great use for these, but that does not mean they're not good insoles! When I put them in pumps I found that they made my feet slip out of the pump even more easily than normal. I don't have strappy sandals that these will fit into. So I currently have them in a pair of mary jane pumps (the strap around the middle keeps my foot in the shoe) but I have yet to wear those anywhere, since they are on the upper limit of the height of heels I can handle (~4" without platform, eek!).
Anyway, so my preliminary review is, because the surface of the insole is slippery and not the gel surface, these insoles will only work in select shoes and not in all shoes. I really wish Dr. Scholl's would go back to their old insole texture - I have a pair that I bought in Asia (Watson's in Taiwan) about 4-5 years ago that I absolutely love - they're only for the balls of your feet, but they had that wonderful non-slip grippy texture that works well in women's high heels (though I suppose they may get to be annoying on a hot sweaty day).
