I have wide feet a bought this to stretch the width of some of my heeled shoes. The listed didn't specify that this was for flat shoes only and I don't know anything about shoe stretchers so didn't realize it myself. When I got it, I quickly realized that it wouldn't work on my high heeled shoes (you need one that's tilted at an angle to fit properly in the shoe while stretching it). The plastic just made it seem cheap and like it wasn't going to last long. I quickly returned it and found a wooden one for high heels on another website (amazon didn't sell it). I have it and love it. I would suggest getting a wooden one as the quality is much better and it seems like it will last much longer.
