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!
My feet always get cold in late Fall, Winter or early Spring road cycling outings. No more - with Castelli Quindici socks! I tried them out and since bought a few more pairs of the same to keep my feet warm, not just cycling but during other outdoor winter activities. Love Castelli gear!
I own several different wool socks but this Quindici Castelli are the softest feeling wool I have ever tried, do it!!!
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.
Very thick, but warm and cozy on the coldest of days!
Nice and warm - no slipping or sliding. comfortable!!
Great blend on these stylish castelli socks, nice height too.
These are midweight socks ideal for cool temperatures on the bike or with casual wear. High quality, attractive and comfortable. But they do seem to run at least i size too small.
Best socks every. I wear them in the winter to warmth and keeps them cool during the summer. Love the extra padding at ball of feet.
As always great Castelli quality. Have worn these in 37 degree weather with toe covers and toes were toasty warm.
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.
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
I ride a lot in the winter here in Utah as long as the roads are clear. Ive been out in 20 degree weather and these wool socks from Castillo keep my feet nice and warm. They ate great under shoe covers and standard cycling shoes.
These socks are very comfortable and warm. I have worn them several times, no complaints.
Use when temperature goes below 60 degrees.
