Running is one of the simplest ways to stay active, but every runner knows that the wrong gear can make even the shortest jog uncomfortable. While shoes get most of the attention, socks are the unsung heroes of running gear–helping prevent blisters, keeping your feet dry, and supporting you mile after mile.
At OS1st®, we design performance socks with purpose-built technology that supports every type of runner. Whether you're training for your first 5k, pushing through long marathon miles, or hitting the trails, there's an OS1st sock made for your run.
Best Running Socks for Beginners
OS1st Active Comfort Socks
Starting your running journey? Comfort is key. Our Active Comfort Socks feature targeted compression zones and medium cushioning to prevent blisters and keep your feet supported as you build your mileage. They're breathable, moisture-wicking, and perfect for easing into running without worrying about unbearably sore feet.
Best Running Socks for Speed Workouts
OS1st Thin Air Performance Socks
When you're working on speed, you want socks that feel like nothing at all. Our Thin Air Performance Socks are ultra-light with ventilation panels that keep your feet cool and dry, even during interval training or hot-weather runs. They give you that "fast and free" feeling without sacrificing support.
Best Running Socks for Trail Running
OS1st Wicked Comfort Merino Wool Socks
Trail running demands durability, moisture management, and temperature control. That's why our Wicked Comfort Merino Wool Socks are built to perform in any condition. Merino wool naturally wicks moisture, regulates temperature, and resists odor–making these the perfect partner for long, rugged miles on the trail.
Best Running Socks for Long Distance & Marathon Training
OS1st Wicked Comfort Socks
When you're logging serious mileage, small problems can turn into big ones. Our Wicked Comfort Socks are engineered for maximum cushion and durability without overheating. They deliver unbelievably soft cushion, blister protection, and moisture control to help keep your feet strong and comfortable through long training runs and race day.
Best Running Socks for Plantar Fasciitis
OS1st Plantar Fasciitis Socks
Plantar Fasciitis is one of the #1 injuries among runners, often caused by repetitive stress and strain on the heel and arch. Our Plantar Fasciitis Socks provide patented, targeted compression and arch support to ease discomfort and reduce pain. They're perfect for runners managing plantar fasciitis, heel pain, or arch strain–helping you focus on your stride, not your soreness.
Best Running Socks for Sensitive Feet
