Warm merino wool-blend kids’ socks with soft terry comfort and reinforced high-wear areas for winter boots and outdoor adventures.
Product Description
Winter adventures feel better when little feet are warm and comfortable from the start. Whether kids are pulling on boots for outdoor school, heading to the sledding hill, or spending the day exploring snowy trails, the Reima Urheilu Kids' Merino Wool Blend Winter Socks bring warmth, moisture management, and soft terry comfort together for active cold-weather days.
The Urheilu combines 35% merino wool with recycled polyester, polyamide, and elastane to balance natural warmth with practical performance. Reima notes that the merino wool blend retains warmth even when moist, while the synthetic fibers help manage moisture during activity. A soft, warm terry interior adds comfort inside winter boots and other cold-weather footwear.
Reinforced areas at the sole, heel, and toe add durability where kids' socks see the most wear, while the mid-calf length provides versatile coverage for everyday winter footwear. Made for cold conditions and especially well suited to waterproof footwear, the Urheilu is an easy addition to the winter layering system for outdoor school, snowy play, family adventures, and everyday exploring.
Why Parents Love It
- Merino warmth for winter days: A 35% merino wool blend helps keep little feet warm through cold-weather adventures.
- Warm even when moist: Reima states that the merino wool blend retains warmth even when damp.
- Soft terry comfort: A warm terry interior adds cushioning and comfort inside winter boots and outdoor footwear.

Built for Real Outdoor Use
The Urheilu is designed for the everyday realities of active winter feet. Kids move between walking, running, climbing, sledding, and simply standing around examining something interesting, and their socks need to stay comfortable through all of it. Merino wool provides warmth while the synthetic fibers support moisture management, helping create a practical combination for changing activity levels.
Reima especially recommends these socks for cold conditions and use inside waterproof footwear. Reinforcement at the sole, heel, and toe helps them stand up to repeated wear, making the Urheilu a useful layer for winter boots, ski days, outdoor school, snowy playgrounds, and family adventures through the colder months.

Ordering bulk with Outdoor School Shop was just as easy and seamless as I had hoped!
