Columbia Montrail Caldorado II OutDry Extreme M

The i-Run team says

Technologies

• Mountain running

  Flat to extreme paths.

  Differentiating elements: Exceptional grip / Structured cushioning / Rigid zones / Stability / Force-Weight balance / Maximum protection

• FluidFoam

  A simple foam responsive from heel to toe. More than classic EVA with 17% additional cushioning. FluidFoam ensures better shock absorption and softer cushioning thanks to the polyolefin elastomer (POE). It also guarantees better energy return thanks to the olefin block copolymers (OBC).

• FluidGuide

  FluidGuide adapts perfectly to the ever-changing terrain of trails and provides superior running comfort thanks to an optimal foot guidance line and stability, regardless of the runner's stance. The different densities of gel allow for a smooth transition between the various foot supports. FluidGuide enables the wearer to benefit from a natural and balanced stride, thanks to a midsole that is both cushioning and protective.

• Trail Shield Co-Molding

  The Trail Shield Co-Molding process eliminates the use of plastics that hinder the natural flexion of the foot and add weight to the product. Each Trail Shield creation is tailored to a specific type of surface and the needs of the user, whether in trail running or mountain racing.

• OutDry

  An impermeable and breathable membrane, seamless, durable, and lightweight.

  The OutDry technology offers dynamic 4-way stretch, without wrinkles, seams, or sealing tapes to fit exactly and precisely to each shoe. The waterproof OutDry membrane is heat-bonded directly to the upper to prevent water infiltration and weight gain in wet conditions. This patented waterproof membrane technology is also more breathable than competing products.
