Sport Shield Roll-on Dimethicone blister prevention

I have been using Sport Shield on my feet for a week, and I like it. The 1.5 ounce bottle nearly doubles its weight to 2.6 ounces in its roll-on packaging, but is very convenient to use. It comes in a towelette form at $12.99 for 10 towelettes, too expensive for my experimentation, and 45+ packets for a long walk would double my pack weight! It is dimethicone in aloe, and available in running stores or on the internet. It is easy to apply and non-greasy for other areas that chafe.

I have used SportSlick for several years, and like the double whammy of silicone and petrolatum (Vaseline). The 3.8 oz. tube is very convenient to carry, lasts more than an entire camino, and the tube packaging does not add much weight. However, it does leave your hands greasy when you have finished applying it. Before that I used Hydropel at about 40% silicone, but it is no longer available. Vaseline and talc aside, I think all the other anti-blister products are snake oil with slick advertising campaigns behind them! Many are quite suitable for after-walk foot treatment, however, or cooking your breakfast in the cases where they contain Crisco.

2Toms also makes a silicone powder, but the running store clerk said it is very messy to use, leaving excess powder everywhere!

I am sufficiently satisfied that I am taking two bottles on my next walk. I will let you know how the longer field test works out.
