these superfeet 3/4 high heel inserts only work well in a few of my lower heels. 1.5-2" they seem to shift my weight back on my heels a bit more and add arch support. in other shoes the dr. scholl's gel inserts work better because they conform to the shape of the sole and add a soft surface to stand on. I will be using both brands and moving the superfeet from shoe to shoe as needed.
