These socks fit my feet perfectly, are very comfortable, and look great. To me, they are a perfect thickness, too. I find most dress socks are far too thin, wear quickly and make heels susceptible to blisters. These are a little thicker than most dress socks I've owned over the years, but still thin enough to be completely appropriate for suit wear. They seem to be high quality and I suspect they'll hold up very well over time. So far, after a couple of washes, they are still like new. I love the colors and diversity of the 5 pack I bought. I also want to credit the seller, Alpha Global Trading, for the obvious care and pride they put into their products and customer service. The delivery was faster than they even committed to, the packaging is fantastic, and most impressive was the ink hand-written note, thanking me by name for choosing them, placed in the box. That is unheard of these days.
