Harald Moistur, lasportiva mountain attack team
"My first thought was that I didn't need these soles. What good are they, I thought to myself. Then I decided to use the insole when training. Since then, I haven't gone on a ski tour without this sole. Simply great. I don't get blisters or pain anymore. I could walk for hours with them. Last season I climbed 200,000 meters in altitude with them."
