First things first
Your most important essential is a fitting running shoe. If you mostly run on asphalt, go for a shoe with high damping that reduces the load on your joints. When picking your shoes, make sure that your toes have enough space both in front and on the sides. Also important for the right shoe choice is your rolling motion: If most of your weight is on the outer edge of your foot when rolling, this is called supination, if your foot rolls inward, it tends to over-pronate. A neutral weight distribution is ideal, you can adjust the support and stability of your running shoes!
