Couldn't get it to stay put in toe box. Not effective.
I couldn't get this device to stay put in the toe box of my shoe once it was inserted and expanded,  and so it was  not useful at all  Am returning it.  (Also,  after having read other reviews, which suggested this device may be too big for some shoes, I even ordered a size smaller than indicated by my shoe size. Even so, it was impossible to jam it all the way into the toe box, and then when it was expanded, it slipped out even farther.)<br /><br />It's a design flaw.  If it had an adjustable wood block on the other end of the threaded bolt, that could be used as an abutment against the back of the shoe and it would keep the device in place. With that design change,  I think this device would work well. But as it's currently designed, I found it useless.
