At OS1st, we know there’s no shortcut to peak performance. It’s built over time—through routine, recovery, and a whole lot of repetition. But when discomfort, injury, or nagging pain gets in the way, progress can stall. That’s where we come in.
Our products aren’t magic, and we won’t pretend they are. You still have to show up, put in the work, and listen to your body. But OS1st can help you stay in the game—supporting the way you move so you can perform at your best without the fear of setbacks.
Protection That Moves With You
Every OS1st sock and sleeve is designed to reduce common stressors on the body. Whether it’s targeted compression around the arch to relieve plantar fasciitis, or gentle support for your knees and calves during long training sessions, our gear works with your body to keep you moving comfortably.
The goal isn’t just to relieve pain after it happens. It’s to protect before it starts. That way, your focus stays on your goals—not your recovery routine.
Designed for Real Life
You don’t have to be a pro athlete to benefit from proper support. You just need gear that keeps up. OS1st is made for the long runs, the tough matches, the walks after work, and the days you’re doing it all. We believe support should fit into your life, not slow it down.
Our socks and sleeves are low-profile, breathable, and engineered for purpose—so you can forget you’re even wearing them. But trust us, your body will feel the difference.
Support Without Distraction
Pain is distracting, and so is gear that doesn’t work. OS1st is designed to get out of your way while delivering relief right where you need it. We target the fascia, muscles, and joints most prone to wear and tear—and we do it without bulk, slip, or irritation.
Because when you’re not worried about injury, inflammation, or discomfort, you can get back to focusing on performance. On purpose.
Relief You Can Feel. Results You Can Build On.
Support doesn’t replace hard work. But it makes it sustainable. With OS1st, you can take each step knowing you’re protecting your body’s future—not just reacting to its past.
Train smarter. Recover easier. And perform at your best, every day.
