No. Wublee features our proprietary Zip Guard Protection™ - a soft medical-grade fabric layer that runs along the entire length of the zipper on the inside. The zipper never touches your skin. After extensive testing, 89% of users report zero irritation even after 12+ hours of wear. Unlike cheap zipper socks that press metal directly against your leg, our engineering ensures comfort from morning to night.

Three critical differences:

(1) Zip Guard Protection™ - our inner fabric barrier prevents the painful skin irritation that makes Amazon zipper socks unwearable.

(2) True 15-20 mmHg graduated compression - cheap versions have inconsistent, weak compression that doesn't deliver medical benefits.

(3) Lifetime zipper warranty - our YKK medical-grade zippers are built to last, not break after a few weeks like inferior brands.

Measure the widest part of your calf and match it to our sizing chart above. Most people find their size matches their shoe size, but calf circumference is the most accurate measure. If you're between sizes or have swelling that fluctuates, we recommend sizing up for comfort.

Remember: our 90-day guarantee means you can exchange for a different size if needed.

Yes. Wublee delivers true graduated compression at 15-20 mmHg - the same clinical specification podiatrists and vascular specialists prescribe. This compression level is clinically proven to improve venous return (blood flow back to your heart), reduce ankle and calf swelling, and prevent the heavy, tired leg feeling. The difference from cheap socks: we maintain consistent compression even with the zipper design. 93% of our customers report visible swelling reduction within one week.

Wublee is designed for Class I compression needs (15-20 mmHg), which is appropriate for: post-surgical recovery (consult your surgeon), mild to moderate swelling, varicose veins, long periods of standing or sitting, and travel. If your doctor has prescribed higher compression (20-30 or 30-40 mmHg) for severe lymphedema or advanced venous disease, please consult them before switching. For most post-surgical and moderate swelling applications, Zippra is ideal.

Many of our customers have diabetes and use Wublee successfully. The key benefits: (1) Easy visual inspection - the zipper lets you check your skin condition without struggling to remove tight socks, (2) No constriction from pulling them on, (3) Breathable fabric reduces moisture. However, if you have advanced neuropathy or open wounds, please consult your podiatrist before using any compression product.

With proper care (machine wash cold, lay flat to dry), Wublee maintains compression effectiveness for 6+ months of daily wear. The zipper is our most over-engineered component - we use hospital-grade YKK zippers tested to 5,000+ cycles. We're so confident in the zipper durability that we offer a lifetime zipper warranty. If your zipper ever fails, we'll replace your socks free of charge.

Absolutely. Wublee is unisex and designed to fit both men and women comfortably. We offer four sizes (S, M, L, XL) and two versatile colors (Classic Black and Neutral Beige) that work for everyone. The compression level (15-20 mmHg) is the standard medical recommendation regardless of gender.
