HOW IT WORKS · DESIGN FEATURES

Built for tired pregnant feet. Tested by 720+ third-trimester moms.

Three engineering choices that make Warm Step the only compression sock pregnant moms actually want to wear.

FEATURE 01 · MEDICAL-GRADE COMPRESSION

15-20 mmHg graduated compression · OB-recommended for pregnancy

Medical-grade graduated compression (tighter at ankle, gentler up the leg) reduces swelling, eases varicose veins, and prevents DVT during long flights or hospital stays.

  • 15-20 mmHg compression · medical-grade, OB-recommended
  • Graduated pressure · tighter at ankle, gentler at calf
  • DVT prevention · safe for long flights + bedrest
FEATURE 02 · BAMBOO-SPANDEX BLEND

Bamboo-spandex · anti-microbial · moisture-wicking · hypoallergenic

Bamboo fiber is naturally anti-microbial — no foot odor even on hot summer days. Spandex stretch holds compression strength through 100+ washes.

  • Anti-microbial bamboo · zero odor, hypoallergenic
  • Moisture-wicking · keeps feet dry through sweat
  • Holds compression 100+ washes · spandex tested
FEATURE 03 · ANTI-SLIP + NO ROLL-DOWN

Silicone grip dots · no roll-down · machine washable

Silicone grip dots at the cuff prevent roll-down even after 12-hour wear. Machine washable on cold cycle, no special care needed.

  • Silicone grip cuff · no roll-down all day
  • Machine washable · cold cycle, air dry
  • S/M/L sizing · fits 5-11 women US shoe size
