Getting into a pair of men's or women's wide toe box shoes (specifically, shoes that are widest at the ends of the toes, not the ball of the foot) is vitally important in preventing additional toe deformities and in creating the circumstances that allow for true toe rehabilitation. So, a wide toe box shoe (which should also, ideally, possess a completely flat and flexible sole) is crucial in preventing a worsening of foot problems, and it's part (but not all) of the foot and toe rehabilitation process.
Most of us have worn conventional footwear with constricting toe boxes for decades, and so it takes some serious work and dedication to regain our natural foot health heritage. For most, simply using wide toe box footwear alone is not enough to achieve optimal toe straightening; many of us possess toe deformities that require a more active approach to remedy.
A toe-spacing device, such as Correct Toes, is an effective tool in reorienting the toes to the position that nature intended. Weight-bearing activity (standing, walking, running) with the toes aligned in their normal anatomical position is necessary to enable natural toe splay.
