A slection of Compeed is always a good addititon to a FAK, and it's not always just for yourself. All the Compeed I have used from my personal FAK have gone on feet that weren't my own.
I have worked as a medic on the Caledonian Challenge for the past 2 years and we got through a lot of Compeed. The only time it doesn't really work is when the boots, socks and foot gets wet and you don't stop and do something about it. I had a competitor come up to me asking if I could look at her foot and do something for the blister she knew she had. She was quite upset about the amount of pain she was in but she was determined to carry on and begged me not to retire her from the challenge, I sat her down and gently took her boot off, then rolled the sock off, what I saw will stay with me for years. She had a fairly bad blister on the ball of her foot, but what really horrified me was the yellow gunk that was squished up between her toes, like she had stepped in custard. I did the only thing I could think of, I laughed. After we both had calmed down a bit(she was very upset) I got her a cup of tea and some biscuits and got the story from her. She had developed the blister and visited the med tent at the last checkpoint and got a Compeed on it before carrying on. Somewhere between there and the checkpoint I was on she got her foot wet and not stopped to empty her boot and change into dry socks and the Compeed had disintegrated and formed the yellow gloop between her toes. I cleaned the mess up, applied a new Compeed and she finished the challenge.
Some Zinc Oxide tape in the FAK is always a good idea too, you can back the Compeed up with it, or use it over a hotspot as it develops. The only trouble is when the blister develops from the hotspot and the tape sticks to the roof and deroofs the blister as you take it off, you then have to treat it as an open wound.
Just my experience of Compeed, hope this helps
) that I start a blister...
