Mid-weight merino socks that provide a good level of warmth for autumn/winter riding
Giro Winter Wool socks
7 10

These Giro Winter Wool socks are warm merino wool socks for the winter, although I'd say they're a fiver overpriced.

They're actually 70% merino wool, the remainder being polyester, Lycra and elastic, and they're reasonably thick. At least the sole, the toe and the heel are thick, made from a toweling weave. The top of the foot is thinner although nothing like as thin as you'll find on a summer-weight sock

The cuff section is ribbed like that of many other sports socks and it's a generous 14cm high. It stays in place rather than slipping down as you pedal and that means there's no danger of any draughts getting in if the ankles of your tights ride up a bit.

I've used thicker cycling socks but these are reasonably warm. I'll find plenty of use for them through the autumn and into the winter. After several weeks' use there's a little bobbling of the wool around the heel, but not enough to worry about.

My only problem with these socks is that I think £20 is too steep. They're good but I still think they're £5 too expensive.

Tell us some more about the technical aspects of the product?

Merino wool is naturally antibacterial and naturally good at wicking sweat away from your skin.

Rate the product for quality of construction:

You can't really go wrong with socks although an elasticated central band over the bridge of your foot and ribbed cuffs hold them in place well.

Rate the product for performance:

You can find thicker, warmer full-on winter socks but these provide good insulation, especially considering that they're fairly low bulk.

Rate the product for durability:

There's a small amount of bobbling around the heel after a few weeks of use, but nothing major.

Rate the product for comfort, if applicable:

They're really comfy without any ridges or folds.

Rate the product for value:

I'd say these should be priced at more like £15.

They're good, although I'd say they're best for intermediate conditions - autumn and spring - rather than the depths of winter, although I guess it depends how cold your feet tend to get.
