The best way to prevent running injuries is to increase your weekly mileage gradually, no more than about 10 percent per week, wear supportive shoes that match your foot type and replace them on schedule, add hip and core strength training, and pay attention to pain that does not ease up with rest.
Vitamin D helps your body absorb calcium and build strong, dense bones, and most adults need between 600 and 800 international units (IU) each day, with many older adults needing more. Low vitamin D levels are linked to bone pain, muscle weakness, and a higher risk of fractures.
The best shoes for foot pain have a firm heel counter, a cushioned but stable heel, a removable insole so orthotics can be added, adequate arch support, and a toe box wide enough that toes are not squeezed. The right pair depends on your foot shape and daily activities, and most walking or athletic shoes should be replaced every 300 to 500 miles or every six to twelve months of regular wear.
Osteoporosis fracture prevention starts with knowing your risk factors, getting a bone density test if you qualify, and combining adequate calcium and vitamin D with regular weight-bearing exercise and a fall-proofed home. These steps, started today, can meaningfully lower your chances of a broken bone later in life.
You may be ready to consider knee replacement when chronic knee pain limits your walking, stairs, or sleep, when daily activities have become difficult despite months of conservative treatment, and when X-rays show advanced arthritis, often described as bone-on-bone. Timing is based mainly on your pain and function rather than a strict age cutoff.
