I am preparing for my 3rd camino. Previously I have worn leather boots. This time I thought I would lighten my load and possibly increase my comfort by wearing trail sneakers or trainers. The pair I bought are partly leather with a mesh type weaving between....Here's the problem, I live in a desert and I have noticed as I walk that the mesh is acting like bellows...each step is sucking in dust!!! At the end of 5 hours walking my feet inside a liner and then a sock are filthy! Has anyone walking in trainers on the camino experienced such problems? Is it just my home environment?! I can always wear my boots again!
