5 Most Asked Questions About Socks for Cold Feet
1. Why do my feet stay cold even with thick socks?
Answer: Material matters more than thickness. Cotton absorbs moisture and loses heat when wet, while natural fibers like wool, cashmere, and alpaca regulate temperature better. Too-tight socks restrict circulation. Sweaty feet lose heat through evaporation—choose moisture-wicking materials. Tight shoes compress socks and reduce insulation.
Solutions: Switch to natural fiber socks, ensure proper fit, layer moisture-wicking socks, address circulation issues with your doctor, and try Sock Geeks Alpaca Bed Socks for maximum warmth.
2. Can I wear thermal socks to bed?
Answer: Yes! Wearing socks to bed helps you fall asleep faster. Warm feet signal your body it's time to sleep, dilate blood vessels for better circulation, and prevent heat loss.
Best bedtime socks: Loose-fitting with no tight elastic, breathable materials (cashmere, alpaca, merino), soft with no rough seams, and not too thick.
Top recommendations: Sock Geeks Alpaca Bed Socks (£28), Cashmere Sleep Socks (£24), and Thermal Diabetic Socks (£11-13).
Avoid if: You have athlete's foot, socks are too tight, you overheat at night, or your doctor advises against it.
3. Are expensive thermal socks worth it?
Answer: Yes! Cheap socks (£5-8) last 6-12 months, costing £15-48 over 3 years. Premium socks (£20-30) last 3-5 years, costing only £20-30 over 3 years.
Premium socks offer: Superior natural fiber materials, reinforced construction, better performance that maintains shape, enhanced comfort, and lower environmental impact.
Worth it when: You wear socks daily, have medical conditions, spend time outdoors, value quality, or want to reduce waste.
Recommendation: Invest in 2-3 pairs of premium socks for daily wear, supplement with budget options for specific activities.
4. How should I care for thermal socks?
Answer: Proper care extends sock life from months to years.
Washing: Wool/Merino—hand wash or delicate cycle at 30°C with wool detergent. Cashmere—hand wash only with cashmere shampoo. Alpaca—hand wash or gentle cycle at 30°C. Bamboo—machine wash at 30°C.
Drying: NEVER tumble dry. Lay flat on towel, reshape while damp, avoid direct sunlight, allow 24-48 hours to dry.
Storage: Fold (don't hang), use cedar balls for moths, keep away from moisture.
Frequency: Wool/Merino every 3-5 wears, Cashmere every 2-3 wears, Alpaca every 3-4 wears, Bamboo after each wear.
Lifespan: Alpaca 5-7 years, Cashmere 3-5 years, Merino 3-5 years, Bamboo 2-3 years.
5. What's the difference between diabetic and regular thermal socks?
Answer: Diabetic socks are engineered for diabetes and circulation issues.
Key features: Non-binding tops (no tight elastic), seamless construction (prevents pressure points), superior moisture management, strategic padding, antimicrobial properties, light colors (spot bleeding easily), and non-restrictive fit.
Who needs them: People with diabetes, peripheral neuropathy, poor circulation, foot ulcer history, swollen feet, or Raynaud's syndrome.
