Before each ultra I coat my feet in some kind of lubricant, usually Body Glide. I looked forward to trying something new. RunGoo is quite different from Body Glide, starting with how you apply it. It comes in a tube that you squeeze onto your feet (or wherever else you might have chaffing or blister issues).
When you remove the cap, the dispenser on the top has these bumps to help spread out the cream. I thought this worked well. I liked how I could spread it all over my feet without ever getting it on my hands.
To me the RunGoo reminded me of a consistency of a combination between diaper cream and Vaseline, nice and smooth. FootKinetics says that it lasts longer because of a mix of waxes that improves endurance, compared to dimethicone products that are thinner. The RunGoo creates a barrier against moisture to prevent blisters.
I read that it is supposed to be applied liberally, and it doesn't need to be spread perfectly even. I realized that the key to using RunGoo is that once you put it on your feet, you need to roll your sock on instead of just pulling it on so the cream stays in place.
The manufacturer says that one thick application will last all day and get you through your workout or race. Based on the runs I've used RunGoo, it has lasted for many hours and gotten me through all the runs just fine, although during a 100 miler where you're out for potentially 36 hours I could see needing a few more applications midway through a race. I think that's to be expected.
I've been pleased with using RunGoo on my feet and feel comfortable taking it with me to use at the Bear 100 next week. I'd suggest giving it a try yourself if you have issues with blisters when you run. You can get more information and order at their website www.footkinetics.com.
