2Toms BlisterShield Advanced Waterproof Blister Prevention, Friction Free Protection Designed Specifically for Feet, Hot Spots, and Calluses, 2.5 Ounce Pouch

I have used this for about 6-7 ultramarathons and I have never gotten a Blister. Great stuff!

Not the best packaging, as other reviews noted but I put it in a locking Tupperware box instead and the product itself works so well. I even used it when I had existing blisters and it made running tolerable and didn’t get any new ones.

Got horrible blisters on the bottoms of both feet when doing triathlons, especially 70.3 distance. Tried variety of techniques to prevent them but nothing worked. Tried this stuff. Put in shoes and socks for the bike leg, more in dry socks and shoes, as well as rubbing into feet, for run leg. I did get some hot spots, but NO BLISTERS.HATE the bag it comes it. Expect to waste a lot unless you find a better container. I prepped my socks and sealed them in plastic bags prior to races. Used a small bottle (like an energy shot bottle) for pouring in my shoes and working into my feet. PITA, but the stuff works, so I'll have to put up with it.

This blister powder is a lifesaver! It works like magic to prevent and soothe blisters, especially during long walks or workouts. Easy to apply, keeps my feet dry, and really reduces friction. I don’t go on hikes without it anymore. Totally worth it! As a bigger person they really help for when I run my marathons.

This stuff works great! I put a level teaspoon in each sock, and if I have problem areas on my feet, I manually apply a small amount to each problem area. For long hikes (more than a couple of hours) I increase the amount to 1-1/2 level teaspoons in each sock. You have to close off the open end of the sock and shake the sock well to distribute. I do this with the heel down to make sure the heel gets adequate coverage. It does take a little time to prepare socks for wearing, and its not cheap, but compared to the amount of time and money I was investing in moleskin and other alternatives, it is a much better overall solution. I have not had a single blister since I started using this product regularly. I used to get hotspots frequently and blisters occasionally - but no more!I hike enough that I am using it up pretty quickly, but to me it's worth it! As mentioned before, I was spending time and money on other alternatives, such as moleskin, foot powder, and other preparations - but I have found nothing that is as effective as this.

This product works fabulous for long runs and running in the rain. Got lucky enough to run two half marathons in the rain and no blisters. Highly recommend. Our local running store recommended this and it is fantastic! If you have trouble with blisters no matter how many different shoes you have tried. Try this, it works!

Not worth it for what its advertised. Bottle is a mess, just makes a mess when trying to use and once you open it, it will never close again. Shame 0 stars ain't an option.

Messy and overpriced but it does help.
