Begin by matching the activity to the sock’s design. For Nordic walking, choose mid-crew socks with cushioning and a snug fit to reduce foot movement. The listed option from Decathlon is a Nordic-style walking sock, sold in a 3-pack, suitable for outdoor activity. Ensure the size matches your foot, and look for comfort features like reinforced toe and heel, and a breathable weave. A well-fitted sock reduces blisters and improves overall performance.

A wool blend with cotton and elastane offers temperature regulation, moisture management, and stretch. In the product listed, the composition indicates a mix that balances softness, elasticity, and durability. Wool provides warmth, while cotton adds softness and moisture absorption, and elastane offers a secure fit. This combination supports long-wear comfort during extended activity and adapts to varied weather conditions without overheating.

For Nordic walking, choose socks with extra cushioning and a secure heel-to-toe hold to prevent rubbing on longer routes. For gym workouts, a lighter, breathable weave and good arch support help with stability during dynamic movements. The Decathlon sock listed is designed for walking but can be suitable for light gym sessions if it fits well and provides adequate support and moisture control.

Wool socks benefit from gentle washing and air drying to preserve elasticity. Use cool or warm water and a mild detergent, avoiding hot water that can shrink fibers. Do not tumble-dry at high heat. Turn socks inside out when washing to minimize pilling and wear on outer fibers. Store in a dry, cool place away from direct sunlight to prevent fiber degradation and maintain softness over time.

Check the brand’s size chart and measure your foot length for accuracy. A snug fit reduces slipping and blisters, while too-tight socks can restrict circulation. If you’re between sizes, consider the activity: walking usually benefits from a slightly looser fit with more cushioning, while gym use may demand a tighter, more precise fit. The current option is from Decathlon and comes in standard ranges suitable for most adults.
