If your legs feel heavy, achy, or swollen after a long day on your feet (or sitting at a desk), you need to try compression socks. Heelbo's knee-high socks provide medical-grade graduated compression. That means they're tightest at the ankle (15-20 mmHg pressure) and gradually get looser up the calf. This gentle squeeze helps your blood vessels work better, pushing blood back up toward your heart to improve circulation. The results? Less swelling, less pain from varicose veins, reduced leg fatigue, and a lower risk of blood clots during long trips or periods of inactivity. They're not just for medical issues – runners, nurses, travelers, and anyone who stands all day swear by them for energy and recovery. This pair is size Large, fitting men's shoe sizes 10.5-12 and women's 12-13.5. They're made from a smooth, breathable blend of nylon and spandex with a silicone band at the top to keep them from sliding down. Just machine wash them. Give your legs the support they deserve!
