Maximum T3 performance now combined with SLS technology. The combination of the two results in a fully reinforced and very hard-wearing sock, with cushioning in the sole that keeps your foot free of blisters during your days of trail running

Testing the Limits The Lorpen research and development team has a clear mission: "TO DESIGN AND BUILD THE BEST TECHNICAL SOCKS IN THE WORLD". As designers and manufacturers of our own socks, we have the knowledge and insight to achieve that goal. Lorpen has been able to expand sock technologies from what was existing in the market. We have set two new technology levels not existing before, two levels only achievable with Lorpen's knitting technology level, T3 and T3 . Regulating Temperature - Maximising Performance Using just one fiber when knitting socks is wasted potential. At Lorpen, we combine different fibers to maximize their warming or cooling properties.
