I learned what to take from reading the Forum and from talking with my wife, who was also a pilgrim. Useful advice was to wear low cut trail runners for shoes and good wool Sox with liners. Also, the admonition to not carry more than 10% of your body weight can be, I think, misleading. That rule should be understood to be an upper limit, not a recommendation that carrying that much weight is advisable. On the Camino, one finds abandoned clothing, equipment, and foot ware that were left behind pilgrims who were tired of carrying so much weight and “things” that they found they didn’t need. It is surprising how little is required to walk the Camino. And whatever one needs can usually be purchased at shops along the way.
