The short version

Leukotape stays on; moleskin cushions. Leukotape is a stiff zinc oxide strapping tape with very aggressive adhesive that survives sweat, water and hours of friction, which is why it dominates ultra medical tents. Moleskin is a soft felt pad with mild adhesive, designed to pad a hot spot rather than to stay put for twenty hours. For prevention on a known problem area, Leukotape. For cushioning around an existing sore spot, moleskin.

Common questions

Should I pop a blister?

Race medical staff often do, in controlled conditions, because the pressure is what stops you running. Doing it yourself with a dirty needle on a trail is how an infection starts. If you must, use something sterile, drain rather than remove the roof, and cover it.

What actually prevents blisters?

Reducing friction, moisture and pressure. That means shoes that fit with room for swelling, socks that manage moisture, keeping grit out, and taping known hot spots before they start. Lubricant helps some people and makes others worse.

When should I see a doctor?

Redness spreading from the site, increasing pain, pus, red streaking up the limb, or a fever mean infection and need medical attention. So does any foot wound in someone with diabetes or peripheral neuropathy, where a blister is a serious matter rather than an inconvenience.

Choose the Leukotape P Strapping Tape if…

You know where you blister and you want it taped before the race. Apply to clean dry skin, round the corners so it does not peel, and practise the exact application in training rather than learning it at the start line. It comes off hard, so an adhesive remover or a lot of patience in the shower is part of the deal.

Choose the Dr. Scholl's Moleskin Padding Roll if…

You want padding around a sore spot rather than a second skin over it. Cutting a doughnut shape so the pressure falls around a hot spot rather than on it is the classic use, and it is genuinely effective. It will not survive many wet hours, so carry more of it.
