As we gear up to hit the trails on a cold winter day, we slip on the Sidi Frost GORE-TEX 2 Cycling Shoe to keep our feet warm and dry no matter what mother nature is throwing at us. Engineered with a GORE-TEX membrane, water is kept out of the shoe while moisture escapes, ensuring our feet remain at a comfortable temperature as we trudge through wet, snowy, or muddy trails. On the bottom of the Frost GORE-TEX 2 is the MTB SR17 sole which stays stiff while pedaling, flexible while walking, and delivers superior grip, stability, and mud dispersion.
