When running, it's important to land on the middle or ball of your foot, rather than your heel. This is known as a "forefoot" or "midfoot" strike. This type of foot strike allows for a more efficient transfer of energy through the foot, and can reduce the risk of injury compared to landing on your heel.

Here are some tips for achieving a proper foot strike when running:

Focus on lifting your knees and keeping your feet low to the ground.
Lean forward slightly at the ankles to encourage a midfoot strike.
Keep your cadence (steps per minute) high, which can also help promote a midfoot strike.
Try to land softly, with a quick turnover, rather than slamming your foot down with each stride.
Start with short distances and gradually increase your mileage, allowing your body to adapt to the new foot strike pattern.
