The Columbia Sportswear Women's Yama Trail Running Shoes were developed with the help of female runners. It redefines performance, comfort and fit for active women – from the shock absorbing air cushion in the heel to the articulated collar system and fully re-engineered women’s-specific heel cup. We’ve also integrated FluidFrame technology for smooth foot guidance, high traction Omni-Grip rubber soles and multi-density Techlite so you stay warm, dry, protected and comfortable during high-velocity aerobic activities in the great outdoors.
