👉 If you are looking for maximum support and want to go further with less fatigue, these are the socks that will accompany you to the very last step.
Knee-High
Total support from toe to knee.

1. Flow+ (4-Season Fabric)
Balanced compression (15-20 mmHg) & All-year-round versatility.

Anti-Slip
Stability "glued" to the ground and maximum grip.
These socks integrate premium silicone grip under the sole of the foot to ensure superior traction. They offer you all the freedom of walking barefoot, encouraging the natural spreading of the toes, but with total security against slipping.
Perfect for:
- Pilates, yoga, and gym workouts
- Daily indoor use on hardwood or tile floors
- Those seeking hygienic protection and grip in studios or communal areas
👉 If you want to improve your balance and challenge your limits indoors with a secure grip, the Pro Grip socks are your silent allies.
Merino Wool
The perfect balance between nature and technology.
The socks are made with a composition of: 50% Merino, 30% Nylon, 15% Acrylic, 5% Spandex.
We studied this specific blend to overcome the limitations of pure wool. 50% Merino Wool guarantees the natural thermoregulation and softness you are looking for, but it is the technical component that makes the difference in durability. The Nylon creates a resistant armor that prevents premature holes in the heel and toes, while the elasticity of the Acrylic and Spandex allows the sock to wrap every single toe without slipping or creating annoying folds.
Year-round protection
They are born with a closed structure without mesh to offer maximum protection from debris and cold. However, thanks to Merino’s unique ability to manage moisture, they keep the foot dry and healthy even during trekking in milder seasons. A dry foot is a protected foot, from both cold and heat.
Coolmax
Unbeatable freshness and feet that stay dry.
Our socks with Coolmax® technology are the ultimate choice for facing the hottest days and high-intensity workouts. Thanks to the special channeled structure of its technical fibers, this fabric instantly wicks sweat away from the skin, transporting it to the outer layer of the sock for ultra-fast evaporation.
Maximum breathability against heat
The combination of the 5-toe design and Coolmax fiber eliminates moisture accumulation in the spaces between the toes, drastically reducing overheating, discomfort, and the risk of blisters. A lightweight, fresh, and incredibly breathable sock, designed to let your foot breathe even when the asphalt or trails are scorching.
Perfect for:
- Road running and trail running in summer
- Intense indoor workouts and high-perspiration sessions
- Those who struggle with heat and seek constant foot ventilation
👉 If you don’t want high temperatures to slow your pace and you demand a dry, fresh, and protected foot from the first to the last kilometer, this is your summer ally.
Every Ortles Run sock is created to offer you comfort, functionality, and freedom of movement. You choose the height, we’ll take care of the rest.
Here you will find the chart with all the specifications for our socks.
Are they summer or winter ones?
Are they summer or winter ones?
Ortles Run socks are designed for four seasons, with a particular focus on spring, summer, and autumn. This means that:
- they offer ideal breathability and moisture management for mild to warm temperatures, ensuring comfort even on long hikes or during sports activities.
- they are not technical socks for extreme cold, but they can still be used in winter conditions depending on the intensity of the activity and your tolerance to cold. Our hikers and athletes have tested them in deep snow up to 40 cm without any particular problems.
Practical advice:
- If you anticipate prolonged stops at low temperatures or particularly suffer from cold feet, combine them with a pair of heavier thermal socks.
- For dynamic activities or fast trekking even in the snow, Ortles Run socks guarantee excellent performance, keeping feet dry and protected.
In summary, Ortles Run socks are an excellent middle ground: versatile all year round, perfect for mid-seasons, and also suitable for harsher climates if combined correctly with appropriate clothing.
