I wear a brace on one foot and use my shoehorn to help me wedge my foot and brace into my shoe.  This shoehorn is too flexible to be of much more use with that than a small shoehorn would be.

I also noted that after about 2 weeks of use, the shoehorn bent about half way in the shoehorn part (the part used to actually guide the foot into the shoe).

Not for me, but if you like flexibility in your shoehorns, maybe this is for you!
