"An ultra-distance insole co-developed by our Salomon Trail Running Team and foot comfort specialists SIDAS. The Trail+ Insoles are a collaborative creation designed for the arduous conditions of ultra running. Each material and its placement have been meticulously chosen for the perfect balance of antislip, long-lasting comfort, lightness, and durability. Benefits: -Antislip: A game-changing feature that holds your feet in place for precision, stability, and support thanks to a combination of high-quality foams, an ultra-thin sandwich construction, and slightly grippy material on the underside of the insole to stabilize you in for the ups as well as the downs. -Underfoot comfort: A flexible pre-shaped sandwich construction with friction-reducing materials on the outer surface ensures a chafe-free and comfortable run. -Lightweight durability: Conceived using an ambitious and well-balanced combination of high-quality foams that are both ultra-thin, lightweight, and extremely durable."
