The lighter weight ULTRA Merino Midweight Mountain sock is the most versatile sock in our collection. Paladin™ protection pads atop the foot relieve pressure from boot laces promoting blood flow for reduced fatigue and improved foot warmth in colder conditions. Elasticated arches and ankles grip the foot for blister-free wear, and a seamless construction provides ridge-free comfort at fabric transitions. Achilles cushioning and strategic padding reduce felt shock from the ground. Designed with right and left specific construction for an anatomical fit.
