This is easier than the smaller (shorter) horns for me to use, and is small enough to travel.  Have to admit I can't use it per the instructions, however.  I have to put my forefoot inside the shoe opening, with the heel lifted, then insert the horn.  Then again, I do this with all my horns, Interestingly enough, my "long" horn (24 in?) I ended up bending by accident just about where the spring is on this one; the long one works better that way.  Which means this spring is a great idea.
