Frequently asked questions

Two sizes, by women's shoe size: US 5-8 (UK 3-6) and US 8.5-12 (UK 6.5-10). Shoe size 8 and below (UK 6 and below), take the smaller size. Shoe size 8.5 and up (UK 6.5 and up), take the larger one. The stretch knit does the rest, no calf measurement needed.

You choose:

• Buy 5 Pairs: one pack with one pair in each color: Cream, Camel, Taupe, Espresso and Black.
• Buy 5 Get 5 Free: two packs, 10 pairs.

The two packs do not have to match: each one can be the assorted pack or a single color (all Cream, all Camel, all Taupe, all Espresso or all Black), and each can be in its own size. Each pack comes in its own clear zip bag.

Pick the 10-pair option in the buy box and the second pack is free at checkout, no code to hunt. You choose a size for each pack right in the buy box. Want one of the packs in a single color instead of the assorted one? Email hello@curvenna.co.uk before your order ships and we set it up.

No. There's no wool in them, and that's on purpose: wool itches, shrinks in the wash and costs twice as much. These are a thick polyester terry with a touch of spandex, smooth knit outside, plush loops inside. All the warmth of wool, none of the itch.

Yes. There's no sewn-in elastic band. The stretch is knitted right into the top of the cuff, wide and soft, so it stays up without digging in. No red lines, no pins and needles, nothing to loosen at the end of the day.

They're quarter-length: the top of the cuff sits just above the ankle bone. You can pull them up a little, but they won't go much higher. With sneakers, slippers or clogs you see the full cuff. With ankle boots, only a bit peeks out.

Actually warm. They're double-thick terry, not a dress sock, not a see-through fashion sock. The plush loops inside trap a layer of warm air around your foot, the way a fleece lining does. Cold floors, boots in the snow, feet in bed: that's what they're for.

Machine wash cold, then hang to dry to keep the loft and softness. If you need the dryer, use low heat on a gentle cycle: high heat is what wears the knit down. Skip bleach.

That is how a lot of customers use them: one pack, five colors, two simple sizes, nothing to guess. A Buy 5 Get 5 Free order arrives as two separate zip bags, so it makes two gifts. And if the size is off, the 90-day guarantee covers the exchange.

It happens, and it usually resolves within a day. First, check the shipping address on your confirmation email. Then look around your door, mailbox and building entrance, and ask your household or neighbors. Carriers sometimes mark packages as delivered a day early, so give it one business day. Still nothing? Email hello@curvenna.co.uk and we will work with the carrier and make it right.

The carrier could not deliver and is holding your package at a local post office or pickup point, usually for 7 to 15 days. Check the tracking page for the location and bring your ID. Not sure where it is? Email hello@curvenna.co.uk and we find it for you.
