** '''Cold Weather Crossings''' Crossing streams in cold weather can introduce the risk of frostbite. In this situation, it may be worth trying to keep your feet dry, even though this is difficult. Using a waterproof sock is probably the best option (waterproof shoes will not be high enough). Something like 'seal skins' are waterproof and will seal against the legs so that they will keep your feet dry even on deep water crossings. My experience with them is that they are not very comfortable and introduce their own issues, so I would only use this option if frostbite was an issue.

* '''Twisting ankles''' Running on trails does put more stress on the feet and ankles than road running. I find that the key is lower leg strength, flexibility and mental ability. The mental ability is being able to adjust your balance when your foot turns and to relax that leg and what I can only describe as 'skip'. By reducing the forces on the foot that is turned, you can avoid serious damage.
