WHY OS1ST
We make the best socks because we understand feet better than anyone else in the room.
Our background in compression technology isn't what we sell. It's why everything we make is better.
We design around the mechanics of the human foot – your arch, your heel, your toe box. Every zone considered. Every stitch intentional.
Not a fabric tube. Never a fabric tube.
- Engineered with purpose, for a purpose
- Designed around specific conditions, not just comfort
- Trusted by athletes, nurses, and podiatrists alike
REAL PEOPLE. REAL RESULTS.
What our customers say
FINALLY! FINALLY! Somebody that knows how to make socks properly and appropriately. I have searched over 20 years for the "right sock" one that I can actually get my foot into comfortably, ones that are the correct length, width and don't leave a strangle ring around my leg. I have tried many great name brands, most of which are great products, but we're not good for MY feet, brands like darn tough, wigwam, injinji, ll bean. I am 57 years old 5'10 240 lbs. I bought the Wicked Comfort, Quarter Crew XL. I have wide high arched hobbit feet complete with large big toe bunions, little toe bunion and bunionettes, have had plantar fasciitis, heel spurs, neuromas, and torn peroneal tendon. These socks are everything that the website says!
I’ve been buying these socks for several years now and I’m genuinely obsessed. They keep my feet cool and provide enough room for my toes to breathe and spread naturally. I switched to these after losing a few toenails while training for a marathon, and I haven’t had a single issue since using OS1st. I currently have about 10 pairs in rotation and only just retired my first set after a few years of heavy use...
I have constantly struggled with my feet sweating throughout the work day and then having a terrible odor afterward. To the point that my wife hated being in the room when I took my boots off. switching to these I sweat but it breathes more and the smell has been cut down. My wife and I thank you!
The Perfect Pink Pairing for Pride! 🌈💖
I am absolutely obsessed with these Wicked Comfort No Show socks in Pink! I bought them in Large, and they fit perfectly. Not only are they incredibly comfortable with amazing cushioning (seriously, feels like clouds), but they are the ultimate accessory for my Speedo Rainbow Pride outfits. The pink is vibrant and matches the brighter colors in the pride gear perfectly, yet they stay completely hidden inside my shoes for that sleek look. They also don't slip down at all! I wore them all day walking and dancing, and my feet felt fantastic. If you want comfort, durability, and style, get these!
Good stuff! Worth the cost. Durable. Comfy. With a right “R” and a left “L” actually written on each sock. The structure dictates the side . With wearable purpose! Wow.
The Very Best
My ratings on a scale of 1 - 10 (10 being the best) of socks: Bombas - 5 Strideline - 8 Thorlos - 9 Os1st - 10 They are the best!!!
At last!!! I have hard to fit, very sensitive feet. I need cushioning but not too thick. These have just the right amount of cushioning and mild compression for my finicky feet. I've tried Bombas and Feetures and these are way better. I ordered three more pair right away. Thank you for these phenomenal socks!!!
Great compression running sock, from a master maker of compression wear
It's great to see OS1st branching out into everyday running gear. OS1st is well known for their compression garments for injury relief and their background shows in this new sock. The socks are individually shaped for left and right feet, ensuring a truly tailored feel. There is a compression band around the arch, which is "moderate" in strength. The top of the foot is extremely well ventilated. If it weren't for the arch compression band, it could be the best ventilated sock ever. If you've worn Feetures socks, these OS1st socks feel more silky, are much better ventilated, and are somewhat less compressive around the arch. As a high quality running sock, there are no perceivable seams. This is a very good first running sock from OS1st. It will work well in the summer for any distance you want to throw at it.
I did not expect the results I have had with these socks…I was very skeptical BUT - I love them! I realized after a couple weeks of wearing them, I have not had any pain from my bunions - no awful aching or stabbing pain. Ordering more!
