These problems are often the result of decades of wearing trendy, toe-squishing shoes, as well as footwear that doesn't provide proper arch support. However, it's never too late to start paying attention to foot health.
Begin by nailing down your shoe size, as your feet will not likely be the same size in your 50s as they were in your 30s. It's a good idea to get feet measured about every year to ensure you're wearing the proper size, which can significantly alleviate foot pain.
Next, shop for sturdy, supportive shoes with a roomy toe box to prevent or slow the progression of problems like bunions and hammer toe.
