Hello! My friend Dave Burdette in Moab, Utah kindly shared some of your Wizard anti-vibratory stickers with me. I am a long distance trail runner and I have been wearing them under the insoles of one pair of my trail running shoes and alternating them with another that has none, throughout my training since last September (I have moved the stickers from an old pair to a new pair as I got new shoes over the season) and I think my legs feel less fatigued when I use the shoes with the Wizardstickers. I wanted to tell you about my experience using the stickers in my running shoes (a soft material) because I see you promote the use of the sticker for metal objects like bikes and engines to reduce vibration. I notice I am less tired after runs where I use your stickers. Your product is amazing.
