We've got answers
Yes. Compression socks are recommended by doctors and OB-GYNs to improve blood circulation and move fluid upward, which helps to:
They are meant to feel snug and supportive, not restrictive.
The compression is firm enough to be effective, while still comfortable enough to wear for several hours at a time. It’s normal for them to feel tight when putting them on, once worn, most women experience relief, support, and reduced heaviness, rather than discomfort.
Choosing the correct size is essential for proper compression.
We recommend following the size chart carefully. If you’re between two sizes, choosing the smaller size usually provides more effective support, as socks that are too large won’t deliver proper compression.
The socks are designed to maintain their fit and compression over time when cared for correctly.
For best results, wear them:
- In the morning, before swelling starts
- During work, walking, errands, travel, or long periods of sitting
- In the evening if swelling or leg heaviness builds up later in the day
Every body responds differently, and results can vary depending on activity level, stage of pregnancy, and individual circulation.
Compression socks are clinically proven the most effective method to improve blood circulation. They are a widely used, non-invasive way to support circulation during pregnancy. If you ever feel unsure about fit, comfort, or effectiveness, we recommend reassessing sizing or consulting a healthcare professional for personalized guidance.
