I'm really insecure about my height so I decided to try these out since they were only like $15, and I'm blown away by how nice they are. The sole takes a bit of ringing in to make it less stiff and more comfortable but after that, it's a really good sole insert. Adding these to my 4in platforms really makes a difference!! I 100% recommend it to anyone that's self conscious and wants a bit of a dfference.
