Quick service that arrived when promised which was important as I needed my 100% wool socks for a winter weather auto race (only natural materials or fire resistant materials allowed). Though these were the 'thinner' version of the 100% wool socks, they were very warm and kept my feet toasty, but not sweaty during 30 degree temperatures at Watkins Glen, NY with snow falling. Can't imagine not having these when standing outside for 9 plus hours a day. They fit in my rather tight driving shoes so would imagine they would also fit in most loafers that are not overly snug. Best part, was wearing chartreuse colored socks at the track. Nomex-white is a bit of a bore. The package was beautiful wrapped and presented with adorable (and I really don't do cute much) little puffy stickers all over it and a lovely handwritten note inside. You might think the socks are expensive, but these are not something you wear for a year or two and toss out. These are truly environmentally friendly since you are going to be keeping them forever. Oddly, to me, the socks didn't even smell after being on all day long including when my shoes and boots were wet from the melting snow (they say this on the website, but originally I was a bit of a doubter on that one). Imagine, no more ice cold feet in the winter! Buy a pair or two to start with, then go buy a couple of pairs for your favorite someone. They're that awesome.
