Piston Compression OTC Sock

Merino-Nylon Blend

$24.00 USD

In Stock & Ready to Ship

Engineered to make a difference in the field, and protect what’s most important on any hunt, your feet! The Piston is constructed with compression throughout the entire calf, specifically designed to lock both the sock and your muscles in place, while promoting circulation. An extra thick footbed for cushioning, not typically offered in compression socks, rounds out the construction – allowing it to be a true game changer for extended backcountry treks.

Comfortable compression!

I have been wanting to buy these for a long time and I finally bought one pair to try out at the hospital for work and to use hunting. After wearing these socks for about ten minutes I wanted to order more. I waited a few hours to see if my feet would sweat and they did not. These socks have great support in the calf , ventilation in the top of the foot , and cushion under the the foot and toes. I have placed an order for three more pairs! They are working great and if you work on your feet all day I would highly recommend these socks!! I wish I bought these months earlier! I can’t wait to try them out in the stand this fall!!

Love most first lite gear but these got holes in them after few uses and wouldn’t exchange. Normal wear and tear I was told. Some have held up. So sticking to darn tough for now.

Hiking/Hunting/All Around Socks

Love the fit. At 6'4" I'm lucky to find a sock that covers the calves. These are the perfect fit for me. I love the tighter compression. I like the fact they are a mid weight sock so I can use them for hiking too and they won't be too warm.

Foot Savers

Compression socks really help with blood flow during the hunt which makes for an easier recovery at the end of the day. For multi-day ventures where you might cover 70 of off-trail miles, I'll take all the help I can get of keeping my feet happy.

Large fit

These socks are great for medium cold weather. Rinse in a creek and dry quickly on a limb and they are ready to go. The only negative is the fit. Size 10 and under, order small. The description says 10 and under small, 10 and over large. Sounds like the magic size is 10. No really. Heal pocket is way up the back of your ankle if you are a 10 and order large. Other than that, great sock.

So far so good.

I’ve been wearing these steady since I’ve gotten them. They are great for wearing with my Lacrosse boots for a day of still hunting. I’m hoping they hold up. The only reason I didn’t give 5 stars is because they are realllly tight. I dried on low heat the first time, but now air dry. The heel looks like it could start to break down quick too, but it might be the boots causing it. They are pretty tell and go to my knees. Will be getting a few more pairs.

Pistol Sock

Was told these are a replacement for the Mountain Athlete Compression Socks, with more padding and increased durability. Mountain Athlete sock were perfect for me, with no fitting or use issues other than they didn’t last as long as other FL socks. These fit different. These are too tall, going up to my mid knee even though 6”1’ so have to roll the top down, really tight on the calf cutting circulation (I have small calves so shouldn’t be an issue), and are looser not as snug on the heel & toe areas as the MA Compression were. Still preferred to every other brand sock but not the same as MA Compression

Way too large and tight

I ordered the smallest size and these socks are way too big, but also too tight which is odd. My shoe size is 9.5 and the heel of these socks ride way up the back of my heel. They are also too tall as they go over my knee, causing me to fold the top down which is not the proper way to wear compression socks. They cut off the circulation to my feet creating pins and needles and my legs aren’t that big. These would be great socks if they had better sizing options as I am smaller than the average guy. I would only buy these if you’re over 5’10 and have skinny legs.
