Compression Socks & Sleeves: Fit & Evidence
Compression
Choose the coverage, then measure
Compression garments apply pressure. Choose by the area you want covered, the task, and the exact product’s size chart.
What to expect from the evidence
A 2025 review of 51 studies found no significant improvement in race time or time to exhaustion when runners wore compression garments during running. Evidence certainty was low to very low. Read the review.
A small marathon recovery trial reported lower perceived soreness at 24 hours. Recovery findings vary across studies. This does not establish injury prevention or a guaranteed performance benefit. Read the trial.
| Type | Useful distinction | Before you choose |
|---|---|---|
| Calf sleeve | Covers the calf and leaves the foot uncovered. | Useful if you prefer your existing running sock. Check permitted activities and wear time. |
| Knee-high compression sock | Includes the foot and calf. | Compare shoe space, calf measurement and the exact sock chart. |
| Targeted foot sleeve or sock | Applies compression around the foot or arch. | A foot sleeve does not replace a night splint, exercise or a heel-pain care plan. |
Fit and use
- Use the current chart for the exact model. For calf products, measure where the manufacturer directs.
- Smooth out folds. Keep the cuff flat rather than rolling or doubling it.
- Try a short period during the intended activity. Remove the garment if you notice new pain, numbness, coldness, discolouration or swelling below it.
- Follow product-specific wear and washing directions. Do not assume a sports calf sleeve is suitable for sleeping or prolonged sitting.
Ask your clinician before choosing compression for a circulation disorder, reduced sensation, unexplained swelling or a medical condition. A sports garment is not a substitute for prescribed compression.
An easier choice
If you like your current socks, compare a calf sleeve first. If you want foot and calf coverage, compare a full sock. Choose the garment which fits your routine and feels comfortable, without expecting it to prevent shin splints or cramps.
