Best socks!

I love these socks! They last for years and they fit so nicely on my feet. I love that I can wear the in tennis shoes or wool boots and they never move!

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.

Excellent all-poly athletic socks for general lifting and HIIT.
Size: Medium, Color: Black/White/Grey
***These are NOT “low” -cut socks as the description in the title states. These are actually “quarter”-cut socks as clearly visible in the picture of the sock itself. “Low” -cut socks are shorter than this height but still visible with a shoe. Also, on the actual UA package of these socks, it clearly states these are QUARTER cut socks.
My review: Gave these UA Performance Tech socks (UAPT) 5 stars since they’re very good but in all reality not the best socks I’ve ever had for lifting and HIIT workouts. That title goes to Nike Dri-Fit MAX socks (DFM)….but these socks are really good. Like Nike’s DFM’s, these UAPT socks come in sizes, halleluah (M, L, and XL). The idea that most athletic sock are sized 6-12 and should therefore fit everyone perfectly is absolutely ridiculous. Your shoes come in whole and half sizes…so socks should at the very least be sized like these UAPT’s and Nike DFM’s…in S/M/L or in this case, M/L/XL. I wear a men’s size 8 shoe and the M (medium) size in these socks was a perfect fit; true to size.
Also, UAPT socks are ALL polyester with Spandex which is ideal and 100% that which you want for athletic socks: wicking with stretch. Cotton socks are the absolute worst thing you could wear to the gym since they’re sponges for sweat and therefore get wet and heavy, cause blisters, tend to stink, stick to skin, etc… IF you prefer cotton socks for athletics, then you don’t understand how performance fabrics work in athletics and training. You do NOT want cotton in your athletic apparel. You want your fabrics that wick sweat away; NOT soak up sweat and hold onto it. Also, the flexibility and stretch of the foot and ankle parts of the sock were both just right. Snug but not too tight. Wicking is perfect, too. Already worn during two 3 1/2 hour workouts and my feet stayed as dry as a desert.
When looking for UA athletic socks on Amazon, I surprisingly continued to find UA “athletic” socks made with mostly cotton which completely surprised me because a serious athletic company should produce an abundance of performance-level socks… i.e. all-poly socks. Thank goodness I finally came across these UA all-poly Performance Techs. The only drawback to these UAPT’s…and it’s a minor drawback…is that unlike Nike DFM’s, these do not come in L & R (left and rights) to specifically match the individual foot shape. Nike DFM socks come in L and R which sets them apart from all other athletic socks…and yet I don’t like supporting a massive monopolistic athletic apparel company like Nike, but they’re the only one that makes THE best athletic sock.
Nonetheless, these UAPT’s are perfect workout/HIIT/lifting socks for the bundle value price of six pair and three colors. If you’re looking to match your new UA or Rock shoes with the appropriate UA athletic sock, then here you go. I chose the black/white/gray mix bundle since I have new pairs of a black and a white version of the same UA-Rock shoe. These UAPT socks are medium thickness so they didn’t take up an exorbitant amount of room in my shoes but they’re thick enough to prevent blisters and provide cushion. Overall they’re very comfortable, hold a good stretch, hold their shape, and seem to be durable but only time will tell.
And since we’re on the black and white sock subject, I couldn’t resist: I read a shoe review about someone angered that his new UA/Rock black shoes (obviously bought for casual wear in lieu of gym use) staining his white cotton socks. First of all, never ever wear white socks (much less cotton white socks) with black athletic shoes! The possibility of staining is always there and the appearance just doesn’t work. However, you can get away with black socks with white shoes in some cases…but never white socks with black shoes. Why? Who knows? It’s just one of those unwritten rules of the gym. And no, I didn’t make the rules…so don’t blame the messenger. LOL!
