Mostly blister relief, cleaned up older heel blisters and then cleaned , medicated then applied some " second skin, a thin film and installed some cushioning around both newer ones. Wrapped everything nicely in those hard to reach places. Gave me some supplies to go. 26 euros
I have a suggestion if you do not receive an answer. Caminoteca store in Pamplona, is run by a many time pilgrim and was a huge help to the lady I was walking with. He trimmed the soles of her shoes to prevent future blisters. I am sure he can assist you in finding the help you need with your feet. Buen Camino
Peaceable Projects Inc. is a U.S.-based non-profit group that brings the vast resources of the wide world together with the ongoing needs of the people who live, work, and travel on the Camino de Santiago pilgrim trail network in Spain.
I was also about to suggest Caminoteca in Pamplona. It’s just down from the Catedral, past the Bistrot café on the corner (side note: they have very weird art installation toilets in the Bistrot). I had a long chat with the owner of Caminoteca the other week about my very small blisters, which I didn’t want worsening. He’s a mine of knowledge, a really lovely man, and has everything you might need for every aspect of the Camino.
