"Superfeet® Run Support Med Arch v2: The Superfeet® Run Support Med Arch v2 is an unisex insole built for runners who need medium arch support during daily training and long runs. The medium arch shape works to reduce stress on your feet, ankles, knees, and back, so you can sustain effort longer without the fatigue that builds from inadequate support. This insole fits into a broad range of running footwear, making it a practical upgrade for anyone seeking a more supported ride underfoot.Aerospring™ Rebound Dual Comfort Foam lines the insole from heel to toe, compressing underfoot and rebounding through each stride so cushioning stays consistent across the run. The EVOLYTE® Carbon Fiber Stabilizer Cap uses a proprietary carbon fiber and polymer blend that responds to compression and springs back to its original shape, delivering responsive support without adding bulk. An accommodating heel cup stabilizes your rearfoot so your foot stays properly positioned during road running and other repetitive-impact activities. The Moisturewick™ Top Cover helps manage odor and is made from 100% recycled materials.Why Our Fit Experts Love It""I slipped the Run Support Med Arch v2 into my daily trainers before a mid-week run and noticed right away how the heel cup kept my foot from shifting around.
