The Microtech UTX-85 Gen IV is a Blade Show Atlanta exclusive configuration built on the UTX-85 platform, 85 percent the size of the Ultratech with the same M390MK blade steel and dual-action OTF mechanism. The Gen IV update brings a new OTF drive system that is the smoothest Microtech has produced on this platform, along with a milled titanium pocket clip with ceramic ball, stainless steel Torx hardware throughout, and a stainless steel glass breaker at the pommel. The handle is machined aluminum with a topographic pattern deep engraved into the surface. Spartan blade in Stonewash M390MK. Dual-action OTF: thumb slide fires and retracts. 3.11" blade, 7.5" overall. Made in North Carolina. Limited lifetime warranty.


Note from Lone Star Knife & Supply: The UTX-85 Gen IV Spartan in Stonewash with the deep engraved topographic handle is the understated version of this pair. The stonewash blade against the engraved black handle keeps the overall look cohesive. Blade Show Atlanta exclusive, M390MK, Gen IV drive system, North Carolina made.

I stay on your foot they don’t slip in your shoe

This is the only socks I wear Under Armour because they stay in place I wear a size 8, but they’re more comfortable with a large instead of a medium, but I wear both because I have them already and you can pull them to stretch them out a little bit

Great fit, truly doesn’t slide off heel
Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium, Number of Items: 3, Color: White/Neutral (3-pairs), Size: Medium
I’ve scoured all the lands looking for a no-show sock that was 1) thin, 2) quality, soft, breathable material, 3) didn’t dig into my feet/heels, 4) doesn’t shrink, and most importantly 5) stays on the back of my heel without a bulky non-slip rubber piece and these check all the boxes! Perfect for low profile women’s work shoes like Keds, etc. Not low enough for most flats though. I wear a women’s size 9.

So good - I’m buying MORE.
Number of Items: 3, Color: White (3-pairs), Size: Medium
I’m gonna give you more detail than you need about why I’m buying these socks again. I’ve been the mom of girl athletes. I’ve been a model and a fashion director. I’ve worn every brand of shoe on the planet and never found a shoe that did NOT find a vulnerable spot on my foot to rub raw. Even my beloved white Jack Purcell sneakers. With that said - I don’t like socks. I’ve bought a TON of them in 35+ years.....all major brands. They shift. They lose their shape. They get holes in them and wear out too fast. Not these. I retired this year, and knowing I’d be in sneakers a lot, traveling, sightseeing ...... I bought these 6 months ago and have worn them constantly. I’ve traveled with them. I’ve washed them in hot water and bleach. The socks are like brand new. They are exactly the right cut so as not to be seen in a basic sneaker. The little silicone patch on the heel stays put. Not once have I had to dig down into my shoe and pull the sock back up. The socks have stayed soft and EXACTLY the same as the day they were new. Like I said - I am back to buy them again. Great quality!
