I don't know why people are complaining about this product being made from flimsy plastic. It needs to bend to fit the curvature of your boots. Do you want pointy edges in your boots? These inserts are strong enough to get into your boots without a problem. I like that you can separate them to fit other sized boots.

My biggest concern when looking for a boot shaper was that it didn't expand the size of the boot in the calf area. I have chicken legs and my boots are as wide as I want them to be. Some of the other boot shapers look like they could stretch out your boots. You won't have to worry about that with these boot shapers.
