CastelliQuindici Wool Sock(Return to Product Page)

Fit is true to size. I'm normally a size 12, or 46/47 depending on sock/shoe sizing. The weight-to-warmth ratio of these socks is awesome. That said, I have not found a wool sock yet that is perfectly warm, but my feet get cold quite easily in 30-40s temps. I find myself wearing 1-2 pairs wool socks, winter boots (Fizik X5) with wind block toe covers and it takes a while for my feet to warm up. No sock is really enough, but the Castelli socks are nice in that they do not add a ton of bulk. The price is also good when compared to Swiftwick and other brands. I do wish the cuff was a little longer, like other brands.

Great socks, but run very small. I read reviews and got XXL and thats 2 sizes above normal. Very warm, and great with toe thingy!

I got a bunch of these and the Venti socks on sale, and loved them but sadly noticed that the bottoms are not at all durable and become threadbare. I hope Castelli learns how to reinforce a sock like everyone else. I was extremely disappointed by these.

I've worn this sock out cycling without booties down to 30 degrees and it keeps my feet warm. It's thin enough that it doesn't crunch your toes in your shoes. I've purchased three pair, and am not happy that they're apparently discontinuing them.

Like the title says, this is the best merino wool sock that I own. I bought a very similar pair from the same brand a couple years ago and those are still holding up. The cold wintry months demanded I buy another pair, and I did so with no hesitation.

Warm and comfortable. My favorite sock for temps in 40s and below. Good look, as well.

i gave a pair of castelli quindici wool socks to a friend for a gift - he loves them. likes the height and the warmth they provide on cold colorado cycling days

Use when temperature goes below 60 degrees.

Nice and warm - no slipping or sliding. comfortable!!

As always great Castelli quality. Have worn these in 37 degree weather with toe covers and toes were toasty warm.

Really nice pair of socks and the price was right.

Comfortable feet make the ride. Castelli delivers again in both comfort and style. Favorite sock of the year. No bunching of toes, and just the right amount of cuff grip.

Real warm down to 45 when shoe covers become necessary.

These are a lot of money but no more than other wool socks and with the great style of Castelli. Other than really cold weather these are adequate for my needs and as stated above I never machine dry. Length is perfect and I like the anthracite color.

Lg fits my size 942 just right. Alway line dry. My go-to sock now for the 3 seasons. The Gregge's are great too, but I like the longer cuff on these. Thanks Castelli for making a great mid-tall wool sock.

Like the socks. They are very comfortable. Also they look great!

Great socks, lite weight but warm. Durable

Great Fit. Great Wicking. Work well with my MTB Shoes for an all day ride.

These socks and a pair of booties will see you down to 32 F with ease. Below that, I recommend a good single malt and a fireplace.

Nice and warm on the days that dips down 30 degrees pair them with shoe covers you can do 30-40 mile ride on cold days.
