The right length depends on where your varicose veins appear. The Endurance Knee-High is Apolla's primary recommendation for varicose veins because its toe-to-knee 20-30mmHg graduated compression covers the full zone where varicose veins present below the knee. For milder lower-leg symptoms or shoppers who prefer shorter coverage, The Infinite Mid-Calf provides the same APMA-accepted 20-30mmHg graduated compression at mid-calf length.
The Endurance Knee-High ($52, 4.92/5 rating) covers toe to knee with seamless toe box construction. The Infinite Mid-Calf ($41, 4.8/5, 800+ reviews) stops at mid-calf and offers WIDE sizing for calves that need extra room. Both are Made in USA, both deliver 20-30mmHg compression, and both are HSA/FSA eligible. The price difference reflects the Endurance's additional coverage length and seamless construction.
Coverage determines where the pressure gradient reaches. Knee-high compression places that gradient across the typical varicose vein zone, including calf and below-knee veins. Mid-calf compression covers the lower leg but does not reach veins that present higher. Neither sock type addresses varicose veins appearing in the thigh, which require thigh-high or prescription compression under medical guidance.
Compliance matters as much as coverage. Some people find knee-high compression uncomfortable in warm weather or during seated periods. A mid-calf sock worn consistently beats a knee-high that stays in the drawer. The length that gets worn daily is the one that manages symptoms.
Endurance WIDE (M-XL) serves shoppers with wider calves alongside varicose vein coverage. As of 2026, both qualify as HSA/FSA therapeutic medical expenses under current IRS guidelines. Explore The Endurance Knee-High's toe-to-knee 20-30mmHg coverage to find your fit. Megan B., an Infinite buyer managing varicose veins, called them “a game changer for anyone with swelling, varicose veins, or ache and pains in their ankles, feet and calves.”
