How to Use Hydrocolloid Tape for Blisters: A Step-by-Step Guide
Hydrocolloid tape has become one of the most popular ways to protect blisters and reduce friction, especially among runners – which is why we launched ours a few months ago (find out more here). But using it correctly makes a huge difference to how well it performs.
Whether you’re treating an existing blister or trying to prevent one before a race, here’s how to get the best results.
Step 1: Clean the Area
Wash the skin with mild soap and water to remove dirt, sweat and oils.
Dry the area thoroughly before applying the tape. Moisture on the skin is one of the biggest reasons dressings fail to stick properly.
Step 2: Cut the Right Size
Using a hydrocolloid roll, cut a piece that’s slightly larger than the blister or hotspot.
Aim for around 1–2cm of healthy skin around the edge.
This helps create a secure seal.
Step 3: Round the Corners
Instead of leaving square edges, trim the corners into a rounded shape.
This simple trick helps reduce lifting and means the tape is less likely to catch on socks or clothing.
Step 4: Apply Without Stretching
Peel away the backing and place the tape gently onto the skin.
Avoid stretching it during application, as this can cause the edges to lift sooner.
Smooth the dressing from the centre outwards to remove any air bubbles.
Step 5: Leave It Alone
One of the biggest mistakes people make is removing hydrocolloid tape too early.
Unlike ordinary plasters, hydrocolloid dressings are designed to remain in place for several days.
Leave it until it begins lifting naturally.
Can You Run with Hydrocolloid Tape?
Yes.
Many runners use hydrocolloid tape during:
Training runs
Marathons
Trail races
Walking holidays
Hiking trips
It cushions the skin while helping reduce further friction.
Can You Shower?
Yes.
Most hydrocolloid tape is waterproof and can stay in place during showers or wet weather.
Simply pat it dry afterwards rather than rubbing it with a towel.
Should You Use Hydrocolloid Tape Before a Blister Forms?
Many experienced runners do exactly that.
If you always develop a hotspot on the same part of your foot, applying hydrocolloid tape before a run can reduce rubbing before the skin becomes damaged.
Common prevention areas include:
Heels
Toes
Achilles
Ball of foot
Common Mistakes to Avoid
Applying to damp skin
Using pieces that are too small
Removing the tape every day
Stretching it during application
Ignoring early hotspots
Final Thoughts
Hydrocolloid tape is simple to use, but applying it correctly helps maximise comfort and durability.
Whether you’re recovering from a blister or preventing one before your next run, a hydrocolloid roll gives you the flexibility to create the perfect-sized dressing for almost any part of the foot.
Keeping a roll in your running kit means you’re always prepared before a small hotspot turns into a painful blister.
