What does COMPRESSIVE mean?
What does COMPRESSIVE mean?
Compressive means that the sock exerts targeted graduated pressure, designed to actively support deep circulation and reduce fatigue.
In the Air Flow model, the compression is of a higher level (Class 2): 30 mmHg at the ankle, which gradually decreases to 25 mmHg at the calf.
This firm pressure helps the soleus muscle – often called our “second heart” – to effectively pump blood upward, counteracting gravity. It is ideal for drastically reducing swelling, heaviness, and chronic discomfort after many hours of standing (at work), during long journeys, or in sports.
In addition, the 5-toe separation improves natural support and balance, and reactivates micro-circulation even in the lowest and most peripheral part of the foot.
What does CUSHION mean?
What does CUSHION mean?
Cushion refers to a reinforcement in the weave, concentrated mainly on the sole of the foot, which makes the sock softer and more cushioned, increasing comfort and reducing impact during walking or running.

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.

Are they summer or winter ones?
Air Flow socks, thanks to their innovative Super Light yarn, are specifically designed for summer and hot climates. This means that:
- They offer extreme breathability and unbeatable moisture management, keeping your leg cool and your foot dry even on the most sweltering days or during the most demanding work shifts. They solve the typical problem with compression socks, which are often too thick and hot.

Swollen and heavy legs? Discover the Air Flow revolution: Class 2 Compression and Super Light Fabric
We designed the Air Flow model to offer you maximum support without making you sweat. The two big innovations? A powerful Class 2 graduated compression (25/30 mmHg) to decisively stimulate circulation, combined with an innovative Super Light fabric that is incredibly lightweight and breathable. The result: deflated, light, and refreshed legs in any season.
Why do I always feel pain and heaviness?
Every morning should be a fresh start, a chance to wake up rested and ready to face the day. But many of us wake up with aches and discomfort because the body is unable to truly regenerate while at rest.
This happens because blood does not circulate well in the areas that need it most.
Let’s be clear...
Modern life tests us more than ever: we work for hours, stand or sit for long periods, and live under constant stress. Over time, poor circulation causes swelling, fatigue, and persistent pain.
Air Flow five-toe socks help counteract these effects by stimulating deep circulation and improving the balance and natural posture of your feet.
The science of graduated compression – how it works
Our legs contain a true “second heart,” the soleus muscle, which helps pump blood back to the heart.
When circulation is poor, the heart has to work harder, leading to fatigue, swelling, and discomfort.
Without proper support:
- Gravity pulls blood downward, promoting pooling.
- Circulation slows down, causing swelling and pain.
- Blood struggles to return to the heart.
With Ortles Air Flow compression socks:
- ✅ Class 2 Compression (25-30 mmHg): A targeted, therapeutic boost. It exerts maximum pressure at the ankle (30 mmHg) and decreases toward the calf (25 mmHg) to push blood upward with force and efficiency. Ideal for those suffering from chronic swelling.
- ✅ Super Light Fabric: Class 2 compression socks are often thick, rigid, and hot. Air Flow revolutionizes this with an ultra-thin, breathable yarn that is easy to put on and perfect even for warmer months.
- ✅ 5 Separate Toes: They improve balance, prevent blisters, and stimulate microcirculation even in the lowest part of the foot for total relief.
The secret behind the Air Flow compression system
Unlike regular socks that offer minimal support, Air Flow’s 3-zone medical compression technology guarantees real results, supporting the muscle without restricting it.
From high-intensity sports to everyday life
Thanks to the perfect mix of medical-grade compression and hyper-breathable yarn, Air Flow socks adapt dynamically to your day:
- 🏃♂️ Intense activity and high perspiration: Whether running, trail running, or engaging in strenuous sports, the Super Light fabric instantly wicks away heat. Muscles receive maximum oxygenation thanks to Class 2, while your feet and calves remain completely dry and moisture-free.
- 💼 Work and Daily Life: Do you spend 8 hours on your feet (like nurses, workers, sales staff) or sitting at a desk? The strong upward thrust of Air Flow cancels out the effect of gravity. You will reach the end of your shift without swollen ankles or heavy legs.
Strong compression, zero discomfort
Some Class 2 socks feel unbearably tight and make your feet sweat. Air Flow offers powerful compression combined with unparalleled comfort.
- Balanced Power: A fit (25/30 mmHg) that stays in place and actively supports fatigued legs.
- Super Light Fabric: Extremely smooth, lightweight, and highly breathable knit. It keeps your legs cool and dry throughout the day.
- Flexible Design: Adapts to your movements without slipping or bunching behind the knee.
- Comfort Cuff: Stays stable at the top of the calf without “cutting in” or marking the skin.
