Blisters can also be caused by extensive outdoor walking while wearing hiking boots or any other footwear which is under-sized. It is not something to feel awesome about but the experience is quite painful and it can retard your movement significantly.
Adhesive Moleskin for Treating Blisters:
Before putting on the boots, you need to cover the blister with a moleskin patchwhich comes with a pile of sheared soft cloth on one side and adhesive on the other. As you know, covering the blister with an adhesive patch is quite painful as the blister rubs against the covering surface. How can we prevent this rubbing of the blister against the surface?
Quite simple! First, cut a patch of moleskin which should be slightly bigger than the circumference of the blister. Then, cut a hole, the size of the blister, in the middle of the patch. Finally, after peeling off the adhesive cover, put the moleskin patch over the blister in such a manner that the blister fits in the hole. This would prevent the blister from either touching the covering surface of the moleskin patch or rubbing against the inner surface of the shoe. For a larger blister, either use multiple layers of the moleskin-with an appropriate hole cut in the middle of the patch-or else, use mole-foam instead of moleskin. Mole-foam is similar to moleskin but has an additional advantage of having a thick underside coating which raises the height of the padding and prevents the blister from rubbing.
It is advisable to remove the moleskin patch at night to allow the blister area to breathe. One may experience severe itching if the patch is not removed at night. It may then be cleaned with spirit or with cotton-wool dipped in a small amount of hot water mixed with Dettol. One can avoid having blisters if care is taken in visiting places where chafing (rubbing) against rough or uneven surfaces is always possible-such as in a cave, historical excavation sites, or even boat rides on rough seas. Also, one should be meticulous about the selection of ones shoes. Comfortable shoes that fit just right can also help in preventing blisters.
