The bunion correctors are a splint or brace that you wear at night and are claimed to correct bunions. But do they?
The research evidence on these is that they can help improve the angle of the big toe by a few degrees after a months wear, so yes they can help, but I would not call that “busting” them. That is small improvement. Is that small improvement worth it?
It probably is worth it. While the improvement may not be much it certainly would have stopped them getting worse as the bunions does end to be progressive. Additionally the bunion correctors will help keep the toe flexible which is also a good thing.
A lot of extraordinary claims do get made for this product and some really stupid lies told about them (see this: Bunion corrector gullibility). Before and after photos as well as testimonials are so easy to fake.
