Castelli Quindici socks



Warm and comfy merino wool socks; a little expensive but the quality is high

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

These socks from Castelli aren’t cheap but they are comfortable and provide a good level of insulation for chilly off-season rides.

They’re made mostly from merino wool – with acrylic, nylon, Lycra and elastic thrown into the mix – and are noticeably warmer than most synthetic socks of a similar weight. Plus, the wool naturally wicks moisture away from your skin to keep your feet feeling fresh when you work up a sweat.

The sole, toe and heel areas are a towelling weave which adds a bit of extra comfort and insulation, and the cuff extends up to about mid-calf height so there’s no danger of the frost nipping at your ankles. Quindici, as linguists will know, is the Italian for 15, and that’s the height of the upper section in centimetres. Oh yes, we’re full of interesting* facts, us.

We’ve been wearing these on and off for a few weeks now, including for some ridiculously cold rides, and they’ve kept our feet perfectly happy. There's a little bobbling on the heel and toe but we’re expecting a decent length of service.

Castelli are making Quidditch socks? Do they float by themselves, or just make it easier to grip on to the broom with your feet?
