Blister Blocker – Stop Blisters At All Costs

From Long runs, races, to hiking, and speed workouts the day does not have to end with blisters. Blister Blocker is made to create a durable anti-friction barrier that protects your feet from rubbing, hot spots, and irritation—before they ever become a problem.

Running is hard enough. Your feet shouldn’t be part of the struggle.

Who It’s For

  • Do you get blisters?
  • Have you tried anti-chafe or other formulas, but still end up with blisters?
  • Do you want to stop blisters on your ultra runs, speed runs, and hot day workouts? 
  • Do you get more blisters than the average person? 

If you said yes to any of these, Blister Blocker is for you! 

How to Apply

Apply directly from the container onto clean, dry feet. Apply generously—don’t be shy. Your feet shouldn’t be completely white, but you should see a visible layer of white balm. Massage into toes, heels, and all high-friction areas for maximum protection.

You may need to wipe off your hands or wash them after massaging it into your toes.

For easier application with lighter protection, use Anti- Chafe.

A Note on Texture

The formula is intentionally thick to create reliable protection. It may leave temporary streaks on the skin during application, but it does not stain clothing and absorbs into your skin once the activity begins.

How Blister Blocker emerged as the best blister prevention in the world

Blister Blocker wasn’t created by guesswork. It was developed through real-world A/B testing on my own feet—left foot versus right foot—during speed workouts, runs in 100° heat, and ultra races up to 65 miles. I tested two formulas at a time, kept the one that caused fewer blisters, and discarded the other. That winner was then tested against a new formula.

After more than 20 rounds of testing—always keeping only the most blister-resistant blend—Blister Blocker emerged as the clear winner.

Once I’d taken the formula as far as I could on my own feet, I started handing it out to as many runners as possible and gathering their feedback. Those real-world results helped guide the final tweaks. That’s how this exact formula was built, and why I’m confident in it.

Proudly formulated and manufactured in Colorado.

Ingredient list

Beeswax, Castor Oil, Cacao Butter, Arrowroot Powder, Zinc Oxide, and Coconut Oil.      No petroleum. No fillers. No artificial fragrances.

How Kramer Ammons (Owner) uses Blister Blocker 

When I first started running, blisters were a constant problem. In my first marathon alone, I ended up with nine blisters—this was before Blister Blocker existed. As my feet have gotten tougher over time, I don’t need it as often, but I still rely on Blister Blocker for:

  • Runs of 20 miles or longer
  • Marathons and ultra races
  • Speed workouts when I need absolute confidence, I won’t blister
  • Hot days, when I know I will sweat a lot

For shorter efforts or lighter protection, I use Anti-Chafe on my feet instead.
