You can only walk and hike as far as your feet can carry you. This means you need to make sure that they are in their best shape before going on the trail.
Take some time to strengthen your feet, wear a light load and walk or hike until you start to feel a hot spot.
Stop for the day as soon as you feel one forming. If you’re prone to hot spots or blisters on certain parts of your feet, try something like Moleskin, Endura Sports Tape, Micropore Tape, Duct Tape, or Leukotape before a blister forms.
You will also need to be able to strengthen your feet’ bones and muscles and the connective tissue of your feet to prevent stress fractures or soft tissue injuries later on.
You can do this by walking barefoot or on uneven surfaces. You can exercise your toe muscles and the muscles on the bottom of your feet. This will help your feet get accustomed to harsh terrain such as that on trails.
