Developed from the Alpha mold, the Omega goes one step steeper on technical ice and alpine routes with expert fast-and-light precision. The rigid thermoplastic carbon fiber midsole puts the foot closer to ice and rock for excellent footwork for a plastic double boot while being light and unobtrusive. The Wet Grip rubber soles provide good adhesion on wet rock and manky snow. Now with a more roomy toe box and thermal mold liner, these are great warmth in frigid temperatures steep terrain climbing boots.
