Most useful item I didn't take but acquired along the way: the Tape That Saved My Shoes!! I'd read many recommendations here on the Forum to take some duct tape or similar - and didn't. Then a couple of days before Burgos I discovered that unnoticed gentle friction had rubbed a hole clean through the lining at the back of both my shoes (Asics running shoes, otherwise super comfortable). My first thought was that the shoes were done for, and I started looking up shoe shop locations in Burgos. Then I thought of duct tape, so after rigging up a temporary "dressing" for the shoes from my first aid kit (also useful!) which got me to Burgos, I went shopping and found some strong tape, similar to duct tape, in one of those "everything" stores. Score!! Fixed it carefully to each shoe, a longish piece starting outside the heel and going up and over and onto the inner sole. I expected to have to change it regularly, even that it might worsen the damage, but it stuck like concrete, never wrinkled, and saw me to the finish line! (Well, as far as Sarria where everything ground to a halt but that's a whooole other story!) So next time I'm taking the tape!
