This is the first review of this product, so I'm putting a little more effort into the overall experience of buying these. Hopefully this helps someone else who is interested in these. Obligatory "I was not paid for this review, and I had to pay for it myself" statement, but I wish I was, these are really nice socks.I bought these socks as a gift for my girlfriend. Shipping was consistent with typical Prime delivery; arrived on time, in good condition, package was undamaged.The size was correct, but unless you're on the border between two sizes that's not usually a problem. If you have big calf muscles you might have trouble fitting them, but they fit my girlfriend just fine... if you're close to the 20" mark it might feel a bit tight though, and maybe I'd suggest going up a size if you're right on the limit of two sizes normally.The entire underside of the sock, where your foot would apply pressure to the ground, is slightly thicker, but not so much it's a pain in the butt. The upper portion is slightly thinner, something that is nice in my regular athletic socks helps breathe and wick away moisture. The description said "arch support", which comes in the form of a well placed strip of elasticised cloth over the arches. The portion around the shins and calf muscles has extra padding and is probably the thickest fabric of the socks, finished with a nicely hemmed elastic strip on the top so it has a little extra something to keep the socks up. The stitching on the inside of the toes is carefully done so it still feels good to wear (you know how some socks have that ridge of stitching that's annoying? These don't.). The upper area that's stylized with the mini barbell icons all looks really good too, better than my regular socks, way better than something like Defeet. I received the socks in blue and the color is consistent more with the first product image shown on Amazon.Overall, my girlfriend is happy to have a pair of these and I'm really impressed with this. I do a lot of sports that are hard on my feet, and the best advice I've ever been given was "it's worth spending extra money on anything that separates you from the ground." This honestly feels like someone made this because they couldn't find a sock that nailed both looks and function and made their own. I like it a lot and would buy it again.
