There are a few things to consider if you enjoy trail running.
This may include blisters, callous, corns and dry skin.
To help prevent these from developing, wear appropriate socks. The best material is predominantly polyester, as this transfers or wicks moisturise away from the skin. This keeps the skin strong and dry, less likely to cause blisters. You can also wear two pairs of socks(to reduce friction); one very thin, without any creases but stretches around the foot and the second pair worn on top, a bit more cushioned. Wearing two pairs creates a barrier, meaning that if there is any friction, it more likely to occur inbetween the two socks rather than directly to the skin.
You may require specific padding to redistribute pressure points in the feet.
Skin and nail preparation
Cut your nails (not too short and not the day before your run)
Moisturise your feet daily to prevent skin irritation from stress. Apply everywhere except inbetween the toes as we want to keep these areas dry. Use a quality urea-based cream.
Address callous and cracked skin if you are not able to manage this.
Make sure that you have a well-fitted pair of trail shoes (a cushioned runner with appropriate grip)
Make sure you have a little room in the shoe, if the feet begin to swell. Ability to adjust lace-technique if signs of swelling and pressure from shoes occur is also important.
If you have any lower leg or foot injuries, your risk of injury may be heightened due to the possible uneven trail surfaces. You may require taping or further advice from your Podiatrist.
