Technology of Twin City socks

proDRI Technology Twin City products bearing the proDri logo are constructed with carefully selected pro-grade fabrics known for their hydrophobic, wicking (i.e. the ability to transport moisture away from the skin) and moisture management attributes. These products retain their insulating qualities, even when wet; and they act to help keep your feet dry. A dry foot retains warmth in the winter and coolness in the summer, and the absence of moisture next to the skin helps to minimize the risk of hot spots and blisters. On top of all this, Twin City's proDri fabrics have been put through rigorous abrasion testing at the Hosiery Technology Center in Hickory, North Carolina, so they’re durable and resilient. With proDri, you get a quick-drying sock that keeps sweaty feet comfortable and won’t fall apart.

Compression Technology Compression zones in the ankle and/or arch of a sock provide a higher level of support, thereby reducing foot fatigue and aiding circulation. These zones also help prevent slippage inside the shoe and insure a proper fit for the life of the sock.

Blister Control Technology - Hot spots and blisters can be debilitating, so these socks offer a healthy dose of preventative in and through unique yarns that naturally reduce friction and wick away moisture, high-splice designs that provide extra shielding in problem areas, and/or dependable liners that add a base layer of protection.

Anti Microbial Technology Twin City's Antimicrobial technology is best defined as built-in deodorant that effectively battles sock odor, even during periods of heavy perspiration. This is achieved this by way of high-grade yarns with embedded antimicrobial agents (not weak and short-lived wash-in treatments) that act to inhibit the growth of bacteria and fungi, the typical culprits behind unpleasant odor. And, you can count on this protection for the life of the sock.

While the material is nice, and worked well (tried it out thinking there was a smaller size, thought I'd give the pair to my son who has a larger foot). While I am a 9-9.5, the heal shouldn't start at my ankle on the back of my leg.

Sock is made of a good material, but the top rolls down after running a bit and somewhat cuts into the leg. I think that partially defeats the purpose of wearing over the knee socks. It does help with the leg guard straps rubbing against the back of the knee but I think that an over the counter compression sleeve from Walgreens or CVS would do the same thing and wouldn't roll down like this sock does. At $20, this is an okay product and one that I would wear but probably would not reorder for next season.

Why do I buy from Ump-Attire.com? Because of their no questions asked return and replace policy. Small issue with the first set of socks, U-A replaced immediately and now I have worn the new set 6 times and I love them. They protect against straps rubbing on your leg but more importantly, and this is a bonus, they fit snug and provide some compression to my legs. My calves feel awesome after a game. 100% Yes, buy these!
