By making the hole bigger than the blister, you are creating a protective well that stops anything from rubbing against it and making it worse. [3] X Research source
The piece of moleskin should fit comfortably around your blister with about ½ an inch (or 1 cm) of material left between the hole and the edge of the moleskin. Apply a second identical layer on top of this if your blister is flush with the surface of the first layer, or if it rises above it.
While moleskin is adhesive, it is not very strong and you risk it peeling off without tape.
You should be able to feel very quickly while wearing them where these uncomfortable spots in your shoes are. If there is a gap between the back of the shoe and your heel, it is likely that chafing and blistering will occur after long or repetitive periods of use.
You want to cover the entire area that is causing pain or discomfort. If it is a strap, measure the moleskin along the entire length of the inside of it. If it’s the heel, the moleskin should reach from the very bottom to the very top of the heel, and span wide enough to cover all chafing areas. The width of this varies person by person and is different for each shoe.
If you are working with a covered toe, stick your index finger over the sticky portion of the moleskin and slide the moleskin forward into the tip of the toe area along the sole of the shoe. [9] X Research source When you push the moleskin in as far as possible, remove your finger and press the tip of the shoe down onto the sticky part of the moleskin to bind them together. Slip your hand beneath the moleskin and with the other hand pull off the rest of the backing, pressing the moleskin up against your shoe as you go.
If the tip of your underwire is bent out of shape, pinch at the base of the bend with one hand and use your other to pry it backwards to unbend it. This may require bending it in various ways until it is roughly the shape it should be.
By massaging the moleskin in your hands before unpeeling the backing you will warm the glue and help it stick to the fabric easier.
To stop the outside of the tape from being sticky, you may wish to apply a layer of moleskin sticky side down to the outside of the microphone and tape. You could do this at the end or before wrapping the pin to the microphone for the final layer.
