Bunions have made doing any kind of exercise without shoes on (or without those prescription insoles) mostly impossible because of balance issues. I don't have too much pain from my bunions, thank god, but they have made doing some activities pretty difficult, especially yoga, which has been the only form of exercise that I've ever enjoyed. Since I have limited mobility in my big toe, I can't use it to balance like most people can, and this became a problem when I did yoga because I would just keep on falling over, and doing balancing positions seemed to make the bunion worse because it meant more time was spent in the misaligned position. This is where the Bunion Aid comes in. I started wearing it to classes, and it has made the biggest difference! I can balance, I don't have to constantly re-position my toes, and the hinge offers enough rotation to do most positions comfortably. It does get pretty sweaty, but the cloth parts are pretty small so washing is not an issue.
As the title suggests, there is a false claim, in my opinion - the one regarding wearing it inside your shoes. Unless you are wearing massive shoes that are 3 sizes too big and too wide for you, you will not fit this contraption inside your shoes in any comfortable way. This is especially the case if you are only wearing one, because then the other foot would feel uncomfortable because you'd be wearing too-big shoes (which would be fine for the foot with the splint, but way too big for the other foot).
This is a minor issue for me, and the BunionAid has helped me out so much and has improved my overall comfort in such a significant way that the inability to wear it inside my shoes just seems so insignificant in comparison, which is why I am not taking a star off for it.
