A dedicated blister treatment kit — moleskin, gel dressings and the tools to deal with a hot spot properly.

Blisters are not serious and they absolutely will turn a good weekend into a limping retreat. They are also the single most common injury on any walking trip.

The trick is treating a hot spot before it becomes a blister. Stop and tape it the moment you feel it, not at the next break.

Sixteen dollars, and it will see more use than any other kit on this page.
