How many pairs of best trail running socks have you tried and tested so far?
You might be lucky to have found the perfect pair already. For most ultrarunners, having to deal with blisters on a regular basis is very common.
Some people naturally have dry skin and are less prone to blisters (I can call myself lucky!) while others suffer even on short runs developing friction burns.
This reminds me of the war stories that some runners could tell about their feet in the desert. Some runners’ feet swelled up to the size of a small ball and blisters covered the whole foot. In those cases there isn’t a lot you can do when heat and sand come into play. Maybe the best socks could have eased some of the discomforts.
Yet, I believe everyone prepared the best they could in order to minimise the risks of suffering from blistery feet.
